2021 HONDA AFRICA TWIN
Model updates: Honda’s definitive full-size adventurer was comprehensively updated for the 2020 with harder-edged off-road performance from a lighter chassis, slim rally-style bodywork and revised riding position; the newly-EURO5 compliant engine’s capacity was also increased, boosting power and torque. A six-axis Inertial Measurement Unit was introduced to manage riding modes and HSTC as well as three additional systems – Cornering ABS, Wheelie Control, Rear Lift Control, plus cornering detection functionality on the DCT version. A new full colour 6.5-inch TFT touchscreen incorporated Apple CarPlay® and Bluetooth connectivity, the new dual LED headlights featured Daytime Running Lights (DRL) and cruise control was fitted as standard.
2021 sees the addition of the much-loved Pearl Glare White Tricolour colour scheme, previously only available on the CRF1100L Africa Twin Adventure Sports version, for the Africa Twin itself.

1. Introduction
It’s been over three decades since the Honda XRV650 Africa Twin first rolled into Europe and while the motorcycle that now bears its name – launched in 2016 as the CRF1000L Africa Twin – was a brand-new machine from the wheels up, it fully inherited the essence and spirit of what made the original so popular.
It was the balance between power and weight that was at the heart of the original bike’s appeal, just as it was for the new model. With its unique, athletic appearance, an enjoyable, usable engine and capable, comfortable chassis, the CRF1000L Africa Twin proved itself a true modern-day all-rounder and has been hugely popular with round-the-world adventurers, around-town commuters and weekend tourers alike.
2018 saw the Africa Twin, in both manual transmission and Dual Clutch Transmission (DCT) form, receive Throttle By Wire (TBW) control plus 3 riding modes, expanded Honda Selectable Torque Control (HSTC) options, as well as intake and exhaust development for improved engine response and sound. The platform also expanded: the Africa Twin Adventure Sports – with the same updates but featuring improved wind protection, greater tank range and longer-travel suspension – extended the machine even further into long-range territory.
Building on strong European (and global) demand for both models, with over 87,000 sold worldwide since its 2016 relaunch, 2020 was a landmark year for the evolution of the Africa Twin. The touring comfort, technology and ability of the CRF1100L Africa Twin Adventure Sports* were further enhanced – adding the option of Showa Electronically Equipped Ride Adjustment (SHOWA EERA™). Meanwhile, the CRF1100L Africa Twin itself was comprehensively redrawn with an aggressive, compact rally style and even sharper off-road focus. Packing more power and torque, it was also significantly lighter – in keeping with the first principles set out all those years ago.

2. Model Overview
The 2020 CRF1100L Africa Twin was given a sharply-renewed focus on off-road core ability, that brought with it the look – and feel – of a true rally machine. Smaller, slimmer and 4kg lighter than the previous model, it offered even more athletic performance, thanks also to changes to the engine, which produced 7% more peak power, 6% more peak torque and much greater strength everywhere in the rev-range. It also became Honda’s first EURO5 compliant engine.
The frame was completely revised and featured a new bolt-on aluminium subframe. The new swingarm, too, was aluminium and based on that of the CRF450R moto-crosser. And at the centre of the Africa Twin, the addition of a six-axis Inertial Measurement Unit (IMU) controlled not only the 7-level HSTC but also 3-level Wheelie Control, Cornering ABS (with off-road setting), Rear Lift Control and DCT cornering detection. An OFF-ROAD setting also joined the URBAN, TOUR and GRAVEL default riding modes.
Tailored for complete control, the riding position featured a new slim-section seat and high-set handlebars. A full colour Multi Information Display (MID) 6.5-inch TFT touch screen brought immersive engagement with the machine’s systems, plus Apple CarPlay® and Bluetooth connectivity. The new Dual LED Daytime Running Lights (DRL) gave optimum visibility, improving safety, and cruise control was added as standard-fit.
For 21YM, the technical package is unchanged, but the new Pearl Glare White Tricolour brings the classic red, white and blue Africa Twin colour scheme back to the latest generation of the machine.
3. Key Features
3.1 Styling & Equipment
- Compact body style designed for off-road, with slim seat and high handlebars
- Multi Information Display (MID) 6.5-inch TFT touch screen
- Apple CarPlay® allows use of Apple iPhone® through the MID
- Bluetooth connectivity, Daytime Running Lights (DRL) and cruise control
Aggressive and compact. Two words that sum up the Africa Twin’s taut rally-style bodywork. And it’s for a reason – to work better off-road. The fixed screen is short to allow for easy scanning of the trail ahead and, with a seat height of 850-870mm, the handlebars mount 22.5mm higher than the previous 1000cc model, giving a more upright riding position and comfortable control, whether standing or seated.
Compared to the CRF1000L, the tail section is slimmer and the seat itself is 40mm narrower, for easier ground reach; its shape is also carefully contoured to allow easier back and forth movement. Low 825-845mm and high, 875-895mm seat options are also available as accessories.
Dual LED headlights are set high, delivering a penetrating beam and also feature Daytime Running Lights (DRL) that automatically adjust to ambient light intensity, improving safety, no matter the conditions. Knuckle guards are standard.
The full colour Multi Information Display (MID) 6.5-inch TFT touch screen keeps the rider in control of all of the Africa Twin’s systems, with each of the riding modes selectable through the top left of the screen. The MID can also be customised to show various levels of information relative to the riding mode chosen and is easy to use even when wearing gloves.
It also incorporates Apple CarPlay®, allowing use of an Apple iPhone® through the touchscreen. Navigation apps can also be accessed and displayed and via a Bluetooth helmet headset calls can be made or received. The iPhone® itself plugs into a USB charging port on the right of the MID. Hands-free wireless Bluetooth connectivity is also an option for an iPhone® or Android device and all control inputs are made from the left-hand switchgear.
The front and rear indicators have an Emergency Stop Signal function. When braking suddenly over 50kph the hazard lights flash to warn other road users a hard stop is in process. They also auto-cancel; rather than using a simple timer, the system compares front and rear wheel speed difference and calculates when to cancel the indication relative to the situation. The auto-cancel feature can be switched off using the MID.
The 2020 update also saw the introduction of cruise control as standard to ease long-distance highway travel.
For 2021 the CRF1100L Africa Twin will be available in the following colours:
Pearl Glare White Tricolour **NEW for 2021**
Grand Prix Red
Matte Ballistic Black
3.2 Engine
- 1,084cc giving 75kW peak power and 105Nm peak torque
- 2020 updates included a new cylinder head, valve timing and lift, throttle body and exhaust
- Manual transmission ratios and gear material were also optimised, saving weight
- The muffler features a variable Exhaust Control Valve (ECV) for improved low-rpm sound and high-rpm performance
The SOHC 8-valve parallel-twin engine’s essential architecture remained unchanged for the 2020 update, but displacement increased to 1,084cc, up from 998cc. And as a result peak power went from 70kW to 75kW @ 7,500rpm with peak torque going from 99Nm to 105Nm @ 6,250rpm. Significantly, the obvious increase in both power and torque made itself felt from 2,500rpm all the way through to the redline.
To create the larger capacity, bore remained at 92mm but stroke was lengthened to 81.5mm (from 75.1mm) with a compression ratio of 10.1:1. Aluminium cylinder sleeves saved weight. Thanks to other detailed weight savings in the transmission and elsewhere, the manual transmission version of the 1100cc engine is 2.5kg lighter (at 66.4kg) than the previous design, the DCT version 2.2kg lighter at 74.9kg.
The 270° phased crankshaft and uneven firing interval create the engine’s distinctive throb and feel for rear wheel traction. For 2020 the cylinder head was completely revised, as was the larger diameter 46mm throttle body; the bore and cylinder pitches were also aligned to create a smooth air intake profile. The ECU setting was updated and the injector angle was modified to deliver a more direct spray into re-shaped twin-spark combustion chambers.
Honda’s SOHC Unicam valve train is a feature of the MX competition-specification CRF450R and the low-set position of the cast camshaft contributes to the compact nature of the cylinder head. For 2020 the valve timing was optimised and the inlet and exhaust valve lift was increased to 10.1mm inlet and 9.3mm exhaust (from 9.2/8.6mm).
To match and deal with the uprated intake efficiency and higher output (thus gas flow) the exhaust end-can of the 2020 model featured a new variable Exhaust Control Valve (ECV) very similar to the unit fitted to the Fireblade. It enhanced both engine performance and efficiency as it opens at higher rpm and gives a pleasing exhaust note ‘pulse’ at lower rpm.
The crankcases are split vertically; the water pump is housed efficiently within the clutch casing with a thermostat integrated into the cylinder head. Manual and DCT versions of the engine share common crankcases with only minor external differences; the water and oil pumps are both driven by the engine’s balancer shafts.
It’s a semi-dry sump design with in-tank lower crankcase oil storage. This allows a lower pan depth that keeps overall engine height low. As the pressure-fed pump is located within the tank where it delivers its oil from, there is no need for a pressure-feed passage. Secondary vibrations are neutralised by the mutually reciprocating motion of the pistons, while primary inertial and coupling vibrations are cancelled by the use of biaxial balance shafts.
For 2020 precision of the front and rear balance gears was improved, allowing removal of their scissor gears; the addition of a crank pulsar ring added misfire detection, important for OBD2/EURO5 compliance. In addition for EURO5 the 02 lambda exhaust sensors were replaced with Lean Air Flow (LAF) sensors in the downpipes to allow for much more accurate measurement of the air/fuel mixture ratio.
The aluminium clutch centre and pressure plate use ‘assist’ cams to ease upshifts and ‘slipper’ cams for deceleration and downshifting; the clutch diameter was reduced in size compared to the previous design and features reduced spring tension for lighter lever feel. The six-speed manual gearbox uses the same shift-cam design as found on the CRF450R to ensure positive changes and shorter ratios were also introduced for 2020. The gears themselves were re-shaped and constructed from stronger material. A quickshifter remains available as an optional extra.
3.3 Engine & Chassis Management Electronics
- IMU-managed HSTC intervention levels optimised for off-road use
- Wheelie Control features 3 levels and IMU management
- OFF-ROAD joins the default riding modes TOUR, URBAN and GRAVEL
- Two USER modes allow for complete riding modes customisation
The Africa Twin’s engine received the benefits of Throttle By Wire (TBW) control in 2018, allowing much finer management of engine output and character as well as expanded Honda Selectable Torque Control (HSTC) for rear tyre grip; for 2020 the system evolved to work in conjunction with a six-axis IMU*.
The electronics system offers 4 levels of power and 3 levels of engine braking. There are seven levels of HSTC with each level’s amount of intervention being optimised to work with real-time input (yaw/roll angle and rate) from the IMU. The spacing of the levels has been optimised to allowing the rider a finer choice of the amount of rear tyre slide for off-road riding. HSTC can also be turned off completely.
Wheelie Control is another feature that was introduced in 2020. Again, with the IMU measuring pitch angle and rate, and controlling engine torque via TBW, the rider can choose between 3 levels of input. Level 1 allows for intended wheel lift but suppresses any sudden movement. Level 3 stops any front wheel elevation and level 2 is mid-way between the two. Wheelie Control can also be turned off completely.
There are four default riding mode settings: TOUR, URBAN, GRAVEL and OFF-ROAD to cover most riding conditions and situations plus two customisable USER settings. Even within the default riding modes, it’s possible to change some parameters – HSTC between levels 1-7 (plus off), Wheelie Control between levels 1-3 (plus off) and DCT S mode shift pattern levels 1-3.
TOUR employs the highest level of Power (1), for touring loaded with pillion and luggage plus mid-range Engine Braking (2) with active on-road Cornering ABS.
URBAN suits wide-ranging riding requirements and uses mid-level Power (2) and Engine Braking (2) with active on-road Cornering ABS.
GRAVEL delivers the lowest level of Power (4) and Engine Braking (3). Cornering ABS is active with an off-road setting; in this setting, the rear brake ABS cannot be switched off.
OFF-ROAD uses lower-mid level Power (3) and the lowest amount of Engine Braking (3). Cornering ABS is active with an off-road setting; the rear brake ABS can be switched off.
USER 1 & 2 modes offer the rider a choice of two distinct personalized setups – choosing between Power levels 1-4 and Engine Braking 1-3, plus HSTC, Wheelie Control and ABS (on-road/off-road) parameters. USER 1 starts out with level 2 Power and Engine Braking, USER 2 uses level 4 Power and 3 Engine Braking.
*See the Chassis section 3.5 of this press kit.
3.4 Dual Clutch Transmission
- ‘Easy and direct’ system offers super-fast gear changes in either Manual Transmission (MT) or Automatic D and S modes
- S mode (with 3 levels) revs higher and downshifts sooner than D, for more aggressive riding
- G switch improves rear wheel traction when off-road
- Incline detection adapts shift pattern depending on gradient
- IMU allows corning detection function for improved shift timings
Honda has sold over 140,000 DCT-equipped motorcycles across Europe since the system first appeared as an option on the VFR1200F a decade ago. Testament to its acceptance in the marketplace, in 2019 DCT versions of Africa Twin (including Adventure Sports version) accounted for 45% of the model’s sales in 2019.
The unique DCT system delivers consistent, super-fast seamless gear changes, and very quickly becomes second nature in use. It uses two clutches: one for start-up and 1st, 3rd and 5th gears: the other for 2nd, 4th and 6th, with the mainshaft for each clutch located inside the other for compact packaging.
Each clutch is independently controlled by its own electro-hydraulic circuit. When a gear change occurs, the system pre-selects the target gear using the clutch not currently in use. The first clutch is then electronically disengaged as, simultaneously, the second clutch engages.
The result is a consistent, fast and seamless gear change. Furthermore, as the twin clutches transfer drive from one gear to the next with minimal interruption of the drive to the rear wheel, any gear change shock and pitching of the machine is minimised, making the change feel direct as well as smooth.
The extra benefits of durability (as the gears cannot be damaged by missing a gear) impossibility of stalling, low stress urban riding, reduced rider fatigue and greater ability to focus on cornering lines and braking points add to DCT’s appeal.
Three modes of operation are available. MT mode gives full manual control, allowing the rider to shift with the handlebar trigger control buttons. Automatic D mode is ideal for city and highway riding, and achieves optimum fuel efficiency. Automatic S mode offers three levels of sportier riding, as the ECU lets the engine rev a little higher before shifting up, and shifts down sooner when decelerating for extra engine braking.
In either D or S mode, DCT offers immediate manual intervention if required – the rider simply selects the required gear using the up and down shift triggers on the left handlebar. At an appropriate time, DCT seamlessly reverts back to automatic mode, depending on throttle angle, vehicle speed and gear position.
DCT for the Africa Twin is also fully equipped to operate in an adventure environment, with off-road functionality enhanced by the G switch accessed via the TFT touch screen display. Activating the G switch in any riding mode improves the feel for available traction and machine control by reducing the amount of clutch slip during gear changes.
Further functionality for the DCT system comes in the form of incline detection, by means of which the gear shift pattern is adapted depending on the grade of an incline to provide optimum control.
A new feature for the CRF1100L Africa Twin’s DCT system for the change to the 1100cc model for 2020 was cornering detection. When the IMU recognises the bike is cornering, the system subtly adjusts the shifting programme for the most natural gear changes.
3.5 Chassis
- A six-axis Inertial Measurement Unit is housed in the centre of the machine
- Light frame, with bolt-on aluminium subframe and light rigid CRF450R-style swingarm for improved rear wheel traction and feel
- Cornering ABS provides sure-footed feel and features an off-road setting
- Optimised damping and spring rates for the front and rear Showa suspension
At the very heart of the Africa Twin’s elevated on- and off-road performance is a Bosch MM7.10 six-axis Inertial Measurement Unit (IMU) tucked away at the centre of the machine, that measures – in real-time – roll angle/rate, pitch angle/rate and yaw angle/rate. It manages rear wheel traction via TBW and HSTC, front braking grip through Cornering ABS, front wheel lift through Wheelie Control and also adds Rear Lift Control.
In conjunction with the addition of IMU control for its 2020 evolution, the strength and rigidity balance of the steel semi-double cradle frame was completely re-examined by Honda’s development engineers to boost off-road ability – at the same time reinforcing its all-round on-road manners. Rigidity around the steering head was optimised to enhance feel for front end grip; the main spars were made slimmer and straighter and did away with the front cross pipe. Frame weight of the CRF1100L Africa Twin is 1.8kg lighter than the previous 1000cc model.
A bolt-on aluminium subframe (finished in red) replaces the integral steel structure of the previous design and is 40mm slimmer at a width of 195mm – crucial for easier ground reach. The aluminium swingarm is 500g lighter than the previous model and took its direction from the design used by the CRF450R. Its improved rigidity improves rear wheel traction and rider feel.
Ground clearance remains 250mm, with wheelbase of 1574mm and rake and trail of 27° 30’/113mm. Wet weight is 226kg.
With stroke length of 230mm the 45mm Showa cartridge-type inverted front fork offers long-travel bump absorption and features revised internal settings to improve both on- and off-road performance. Rebound and compression damping are fully adjustable. A cast aluminium top yoke and forged bottom yoke – joined by hollow aluminium stem shaft – clamp the fork legs with two bolts each top and bottom.
Matching the front suspension, the Showa rear shock delivers 220mm axle travel and features a 46mm cylinder and remote reservoir for stable damping control under extreme off-road riding conditions. Spring preload can be adjusted via a dial on the shock body; rebound and compression damping are also fully adjustable.
The swingarm pivot points’ inner plates use 600MPa high-strength steel and the upper cross tube that connects them acts as the rear shock upper mount (through a pillow-ball joint) improving feel for rear wheel traction.
The IMU takes in lean angle, deceleration (from front/rear wheel speed sensors) and incorporates the slip rate of the front and rear wheels to manage braking pressure through the ABS; likewise if it detects sudden rear wheel lift, it finely controls brake force to maintain stability. When stationary the rear ABS can be cancelled for off-road riding.
Compact two-piece radial-mount four-piston calipers work dual 310mm ‘wave’ floating discs through sintered pads. The rear 256mm ‘wave’ disc features hole punching and shaping. 21/18-inch front rear (stainless steel) spoked wheels wear 90/90-21 and 150/70-18 tyres. Block pattern tyres (Continental 90/90-21M/C 54S and 150/70B 18M/C 70Q, rated at 180km/h and 160km/h respectively) are approved for fitment.
4 Accessories
The range of Honda Genuine Accessories for the Africa Twin includes premium (42L) aluminium top box and panniers plus large (58L) plastic top box and panniers, two seat heights (a lower 825-845mm and taller 870-895mm option), touring screen, radiator guards, engine guards and side pipes, knuckle guard extensions, heated grips and an ACC charging socket.

CLASSIC AFRICA TWIN COLOUR SCHEME AND EURO5-HOMOLOGATED CB650R AND CBR650R JOIN HONDA’S 2021 YEAR MODEL LINE-UP
- Pearl Glare White Tricolor paint scheme to be made available on the CRF1100L Africa Twin
- CB650R and CBR650R homologated for EURO5 and now come with Showa’s ‘Big Piston’ front forks
Following the announcement of new colour schemes and EURO5 homologation for the CB500F, CB500X and CBR500R, and the introduction of the new CB125F, Honda Motor Europe today confirms three more additions to its 2021 year model line-up.
The CRF1100L Africa Twin will now be available in the classic Pearl Glare White Tricolour paint scheme synonymous with the original XRV650 Africa Twin, which was launched in 1988 during Honda’s run of four consecutive (1986 to 1989) victories in the Paris Dakar Rally with the NXR750 – the inspiration for the Africa Twin.
The tricolor look is currently available only on the continent-crossing ‘Adventure Sports’ version of the Africa Twin. With over 70% of customers choosing it ahead of the Matt Ballistic Black Metallic option, the evocative paint scheme will also now sit alongside the ‘CRF’ Grand Prix Red and Matt Ballistic Black Metallic colourways of the Africa Twin itself.
In 2019, the Africa Twin’s 1100cc engine made the CRF1100L Africa Twin the first Honda motorcycle to meet EURO5 emission standards. Now, further news for Honda’s 2021 model line line-up comes with EURO5 homologation for the CB650R and CBR650R four cylinder middleweights, thanks to revised ECU, cam lobes and intake timing, as well as the addition of a crank pulsar.
Both the CB650R and CBR650R will now also come equipped with Showa’s Separate Function Big Piston* (SFF-BP) 41mm USD forks for improved feel, bump absorption and control, and a number of other detail improvements to enhance comfort, usability and practicality.

21YM HONDA CB125F
Model updates: Honda’s perennially popular entry-level CB125F is a brand-new motorcycle for 2021 and a huge 11kg lighter. Its low friction eSP (‘enhanced Smart Power’) engine significantly improves fuel economy while maintaining performance and now features an ACG starter. The revised bodywork takes styling cues from bigger CB stablemates, and equipment includes an LED headlight, centre stand and digital dash with ECO meter.

1. Introduction
An entry-level 125cc motorcycle has to be a multi-faceted machine. To some it represents the most economical way of getting from A to B, both in terms of initial affordability and running costs. To these riders it must be durable, easy to live with and economical: simple, trouble-free transport at its most fundamental.
But to many new riders a 125 is the start of their motorcycling adventure, their first ‘real’ bike. So, it must deliver all of the above, plus everything else that a motorcycle should – the excitement, freedom and instinctive pleasure that two wheels bring to everyday life. Yet it also has to be easy for a novice to manage as they learn, with a build quality and styling that instil tangible pride of ownership.
For any manufacturer, welcoming and introducing fresh entrants to their brand is important. The right initial experience can lead to a lifelong association, and the CB125F has long served this function for Honda – a tough, user-friendly entry-level motorcycle that offers the perfect first rung on the ladder. The CB125F was a new model name for Honda in 2015; it maintained the previous CBF125’s core strength of robust simplicity but built strongly on that strong foundation in terms of quality, ease of use and style.
For 2021 the CB125F is renewed again, with a complete refresh that makes it even more desirable and cost effective. The new CB125F is a great bike to simply get you where you need to be – or from where to begin the ride of a lifetime.
Mr. Ken Tomiyasu – Large Project Leader (LPL) 2021 CB125F:
“For us, benchmarks are important. So, we have set about a quiet revolution with our all-new CB125F, keeping its useful around-town performance but adding much greater fuel economy. It also features advanced low-friction technologies in the eSP engine, confident handling from its chassis, and looks that an owner can be really proud of. We are very proud that so many people will begin their motorcycling journey with Honda on CB125F, and know that it will provide pleasure and practicality in equal measure.”
2. Model Overview
The new CB125F is a serious small machine, whose development involved the filing of no fewer than 19 patent applications. Made at Honda’s Atessa facility in south east Italy it offers a huge jump in fuel economy from its air-cooled enhanced Smart Power (eSP) engine, with no loss of performance.
It’s also 11kg lighter, with a redesigned frame and an up-to-date, big-bike re-style; an LED headlight and revised digital dash are quality finishing touches. The 2021 CB125F will be available in the following colour options:
Splendor Red
Pearl Cool White
Black
3. Key Features
3.1 Engine
- New enhanced Smart Power (eSP) engine offers 27% extra fuel economy, with no loss of performance
- Low friction technologies include offset cylinder, needle bearings for the roller/rocker arms and piston oil jet
- ACG starter also generates electricity and contributes greatly to the engine’s 7kg weight loss
- 5-speed gearbox and sealed final drive chain
The CB125F’s new air-cooled, 124cc 2-valve SOHC single-cylinder eSP (‘enhanced Smart Power) EURO5-specification engine has been engineered from its inception to maintain optimum performance for busy urban streets but with extra, serious frugality and supreme reliability.
Peak power of 8kW is delivered @ 7,500rpm, with peak torque of 10.9Nm @ 6,000rpm (as opposed to 7.8kW @ 7,750rpm/10.2Nm @ 6,250rpm). Bore and stroke is set at 50 x 63.1mm, with compression ratio of 10.0:1. Standing start acceleration over 200m 12.4s, but more importantly, the fuel efficiency is vastly improved – leaping from 51km/l to 66.7km/l, giving a potential range of over 700km from the 11L fuel tank.
Honda has developed its eSP engines – and the engineering that goes into them – on a growing range of 125cc scooters over the last 5 years. The focus is around building in, from a clean sheet, low-friction technology to every facet of the engine; the CB125F’s eSP engine benefits hugely from eight years of accumulated know-how.
And it starts with weight. The new eSP design is 7kg lighter than the engine it replaces. Its cylinder is offset, reducing friction between the piston skirt and bore, while the piston itself is cooled by an oil jet from underneath, again reducing friction. Valve operation is via rocker-roller arms equipped with needle bearings.
An Alternating Current Generator (ACG) is also part of the eSP formula and combines electricity generation with starting duties, saving weight while simplifying layout. The effort needed to start the engine is reduced thanks to a swing-back system that returns the crank to its position before air intake – giving the engine a ‘running’ start – and a decompression mechanism that negates cranking resistance due to compression. In use the ACG starter is extremely quiet. The gearbox is 5-speed and final drive is via sealed chain.
3.2 Chassis, Styling & Equipment
- New tubular steel frame saves 1.7kg; twin rear shocks are preload adjustable
- Sharp re-style adds big-bike presence and extra CB family DNA
- The nose fairing houses an LED headlight and digital dash
- Wet weight of 117kg is 8.6% lighter than the previous model
The new tubular frame uses high-tensile steel in its construction and is 1.7kg lighter. It suspends the engine from a sturdy central spine and features geometry that provides the best balance between ride comfort and straight-line stability, with a focus toward light steering input and sporty feel at all lean angles. Rake and trail are set at 26° and 92.4mm, with wheelbase of 1280mm and wet weight is 117kg, a full 11kg lighter.
Dual rear shocks offer 5-step spring preload adjustment and complement the 31mm diameter telescopic fork’s compliance and ride quality; stylish 18-inch die-cast aluminium split-spoke front and rear wheels increase stability and ride quality over rough city streets. Tyres are sized 80/100 front and 90/90 rear. A 240mm front disc is worked by a dual piston caliper, with back up from the 130mm rear drum; both are managed by two channel CBS.
The 2021 CB125F wears aggressive new styling, with echoes of larger bikes in the CB family, around its redesigned chassis. The broad-shouldered fuel tank and silver-finished shrouds in particular take their cues from the CB-R Neo Sports Café family, while a CB500F-influenced angular nose fairing and blacked-out fly screen provide some wind deflection, and a sharper attitude. It also houses a new LED headlight and digital dash that displays the information that matters, including a gear position indicator as well as real-time and average fuel economy, distance to empty and ECO indicator, for when riding in the most efficient way. The start/stop button is an integrated switch (the previous model did not feature a stop button as standard) as is the high beam/passing switch.
The engine, exhaust downpipe, fork lowers and wheels are blacked out, underlining the strong lines and bold paintwork. The muffler too, is blacked out but also finished with a chrome heat shield. Bright red detailing is to be found on the shock springs, spark plug HT cap and HONDA, picked out on the left-hand engine cover. Other quality finishing touches include 3D Honda Wings on the shrouds and mirror/indicator shaping that emulates the design language of the whole machine.
With its intended use as an everyday commuter, gateway machine to the world of motorcycling – and riding school stalwart – the CB125F’s riding position is upright and relaxed, with more forward-set footpegs and wide tubular handlebars giving optimum control, rider confidence and all-round visibility. Seat height is 15mm higher at 790mm and offers room for two adults comfortably; a passenger grab rail is also standard, as is a centre stand.

V-STROM 1050XT WINS MOTO JOURNAL
MOTORCYCLE OF THE YEAR AWARD
The new V-Strom 1050XT has picked up Moto Journal's award for motorcycle of the year, with a rating of 91 out 100.
The respected French title handed the award of moto de l'année to the new-for-2020 Suzuki V-Strom after a thorough evaluation focussing on the bike's ability, spec, and price.
The new V-Strom 1050XT uses the proven 1037cc V-twin engine from Suzuki, but meets Euro5 emissions regulations while increasing peak power to 107.4PS (79kW), a 7% increase over the previous generation.
And while the design harks back to the original and iconic DR Big and pays homage to that original adventure machine – both bikes were designed by the same person – a thoroughly modern and comprehensive suite of electronics dubbed Suzuki Intelligent Rider System (SIRS), sees the V-Strom 1050XT equipped with cruise control, lean angle-sensitive ABS, two ABS modes, slope-dependent control, load-dependent control, and traction control, plus a ride-by-wire throttle and three power modes.
FREE CITY PACK KIT WITH NEW V-STROM 1050
Suzuki is offering a free City Pack accessory kit with the new V-Strom 1050.
The pack – which usually retails for £549 – includes a spacious 55-litre top box, all the necessary mounting kit and a centre stand.
It means the V-Strom 1050, already lauded as one of the best-value adventure bikes on the market thanks to its RRP of just £9,999, now offers even more practicality. The free City Pack makes the true all-rounder an ideal tool for both weekend getaways and the daily commute, with plenty of space to keep your clothes and laptop for work while avoiding crowded public transport.
Launched this year the V-Strom 1050 uses Suzuki’s 1037cc V-twin engine which has been upgraded for Euro5, making 7% more power (107PS) whilst delivering strong liner torque from tick over to red line and 57.65mpg, giving an impressive 250mile range from its 20L tank. There are three power modes and three traction control settings to keep everything in check, plus the ability to turn the traction control off. It also gets Suzuki’s easy start and low RPM assist, which aids setting off and makes light work of town riding.
SUZUKI TO HOST SUPER 70 TEST RIDE WEEKEND
With the impending release of the ‘70’ registration plate in September Suzuki has announced a Suzuki Super 70 Test Ride weekend on 11-13 September, plus the chance to win one of three V-Strom 1050-themed Arai Tour-X4 helmets worth £649.
With almost all of Suzuki’s on-road dealer network taking part there will be no shortage of models to demo, including the new-for-2020 V-Strom 1050 – which currently comes with a free City Pack – and V-Strom 1050XT. Both bikes have the latest Euro 5 version of Suzuki’s fabled 1037cc V-twin, which now puts out 107PS. They also get a three-stage traction control system and three engine power modes. The XT adds cruise control, hill hold assist, load and slope-dependent control linked brakes, two ABS modes plus lean angle-sensitive ABS.
Those that take a test ride can enter a prize to draw to win one of the Arai adventure helmets by posting a picture of themselves with the new V-Strom to the SuzukiBikesUK Facebook page or by tagging @SuzukiBikesUK on Instagram or Twitter, and using the hashtag #SuzukiSuper70.

21YM HONDA CB500F
Model updates: Following a ground up redesign in 2019, Honda’s A2-compatible mini-streetfighter receives new graphics and two new colour schemes for 2020. The CB500F is also now homologated for EURO5

1. Introduction
The naked CB500F – originally launched in 2013 alongside the adventure-styled CB500X and fully-faired CBR500R – has proved that one of Honda’s tried-and-trusted formulas for building popular motorcycles has lost none of its relevance.
That formula? An entertaining twin-cylinder engine wrapped in a simple, lightweight, sporty chassis, which is as much fun for an experienced rider as it is for those still building their riding career. And while a 35kW peak power output makes it suitable for A2 licence holders, the CB500F offers so much more than ‘entry level’ performance.
While its compact dimensions and welcoming manners make it an easy machine to manage, ride and learn on, those same attributes also make it a genuine pleasure for those – whether stepping up from a 125 or coming down from a bigger machine – who want to explore just what it can do at the weekend. Sensible running costs, whatever the situation, add strongly to the appeal.
In 2019, the CB500F was redrawn with uncompromising lines that elevated its technical and mechanical aspects, and a host of upgrades that enhanced the riding experience even more. 2020 sees the introduction of updated graphics, two new striking colours and EURO5 homologation for one of Honda’s most popular machines.
2. Model Overview
The CB500F’s 35kW engine is A2 licence-compatible and benefits from the 2019 upgrades to the inlet, exhaust and valve timing, which added 4% more power and torque between 3-7,000rpm compared to the previous model, and were accompanied by an enhanced exhaust note and a new assist/slipper clutch.
LCD instruments include a Shift Up and Gear Position indicator, and all the lighting is LED. While both engine and chassis are unchanged for the EURO5-homologated 2021 year model, two bright new colours freshen up the appeal.
3. Key Features
3.1 Styling & Chassis
- Aggressively-styled bodywork
- Tapered handlebars for excellent control and feel
- LCD instrument display, with Gear Position and Shift Up indicators
- Full LED lighting
- Two new colours for 2020.
For its 2019 evolution, the CB500F’s naked faired form evolved front to rear, exuding a new-found aggression. Led by the penetrating headlight design, the machine’s stance is low-set and ready for action; the side shrouds interlock with the fuel tank and fully emphasize the engine, while the side covers and seat unit continue the theme of muscular angularity.
Tapered handlebars give intuitive feel and leverage. LCD instruments feature a Gear Position and Shift Up indicator; this is set to a default 8,750rpm but can be adjusted in 250rpm increments between 5-8,750rpm
The 35mm diameter steel diamond-tube mainframe is unchanged for 2020. It’s light and strong, with a tuned degree of yield that gives plenty of feedback to the rider as road surfaces change. The shape and position of the engine mounts, plus the frame’s rigidity balance also reduces vibration.
Wheelbase is 1410mm and rake and trail are set at 25.5°/102mm, giving nimble, yet confidence-inspiring steering. Mass centralisation, with the engine in close proximity to the swingarm pivot point, delivers turning agility and optimum front/rear weight distribution ensures stability. Kerb weight is 189kg.
Seat height is low at 785mm, making the CB500F very easy to manage and its neutral riding position comfortably accommodates riders of any height. Overall dimensions are 2080mm x 790mm x 1060mm, with 145mm ground clearance. The fuel tank holds 17.1L including reserve, and, combined with the engine’s excellent 28.6km/litre fuel economy, gives a range of 480km (over 260 miles).
The 41mm preload-adjustable telescopic front fork, with 120mm stroke, delivers a compliant yet controlled ride and gives great feel for front tyre grip. A single-tube rear shock absorber (as found on larger capacity sports bikes) with a large-diameter piston, ensures excellent suspension response and temperature management. It has 9-stage spring preload adjustment and works through a rigid box-section steel swingarm, which features pressed steel chain adjustment end-pieces. Final drive is via sealed 520 chain.
Lightweight, 17-inch cast aluminium wheels employ hollow cross-section Y-shaped spokes. Front wheel width is 3.5inch with a 120/70-ZR17 tyre, the rear 4.5inch with a 160/60-ZR17 tyre. A single front 320mm wavy disc and two-piston brake caliper is matched to a 240mm rear disc and single-piston caliper. ABS is fitted as standard.
The CB500F will be available in the following colour options:
Grand Prix Red
Matt Gunpowder Black Metallic
Candy Caribbean Blue Sea **NEW**
Candy Moon Glow Yellow **NEW**
3.2 Engine
- Lively twin-cylinder power plant’s internal architecture mirrors that of the 2019 CBR1000RR Fireblade
- · Usable power and torque across the range
- Sportier sound from the dual-exit muffler
- Assist/slipper clutch eases upshifts and manages downshifts
- Now Homologated for EURO5
The CB500F’s A2-licence friendly, 8-valve liquid-cooled parallel twin-cylinder layout offers a well-proportioned balance of physical size and willing, enjoyable power output, with an energetic, high-revving character and zappy top end.
Already strong off the bottom, the 2019 engine upgrades saw faster acceleration through a boost in low-to-mid-range power and torque in the 3-7,000rpm range; with a 4% improvement coming via altered valve timing – with ‘close’ timing accelerated by 5° – and lift increased by 0.3mm to 7.8mm.
Feeding the PGM-FI fuel injection is a more-or-less straight shot of airflow through the airbox and throttle bodies – the 2019 upgrade saw the battery re-positioned further away from the rear of the airbox intake duct to allow greater airflow. The exhaust muffler features dual exit pipes, giving a sporty sounding edge to each pulse. Peak power of 35kW arrives at 8,500rpm, with 43Nm torque delivered at 7,000rpm.
Bore and stroke is set at 67mm x 66.8mm and compression ratio is 10.7:1; the crankshaft pins are phased at 180° and a primary couple-balancer sits behind the cylinders, close to the bike’s centre of gravity. The primary and balancer gears use scissor gears, reducing noise. The crank counterweight is specifically shaped for couple-balance and its light weight allows the engine to spin freely, with reduced inertia.
Acting as a stressed member, the engine complements the frame’s rigidity with four frame hangers on the cylinder head. Internally the cylinder head uses roller rocker arms; shim-type valve adjustment allows them to be light, for lower valve-spring load and reduced friction.
A silent (SV Chain) cam chain has the surface of its pins treated with Vanadium, reducing friction with increased protection against wear. Inlet valve diameter is 26.0mm with exhaust valve diameter of 21.5mm.
The piston shape is based upon those used in the 2019 CBR1000RR Fireblade to reduce piston ‘noise’ at high rpm. Friction is reduced by striations on the piston skirt (a finish that increases surface area, introducing gaps in which oil can flow for better lubrication). As with the CBR1000RR, an AB1 salt bath process, used after isonite nitriding, forms a protective oxidisation membrane.
The ‘triangle’ proportion of crankshaft, main shaft and countershaft is very similar to that of Honda’s four-cylinder RR engines and much of the internal structure and engineering is taken directly from the 2019 CBR1000RR.
The crankcase uses centrifugally cast thin-walled sleeves; their internal design reduces the ‘pumping’ losses that can occur with a 180° phased firing order. The oil pump features improved aeration performance, with reduced friction; a deep sump reduces oil movement under hard cornering and braking. Oil capacity is 3.2L.
The CB500F’s six-speed gearbox is very close to that of its RR cousin and uses the same gear change arm structure and link mechanism. Introduced in 2019, an assist/slipper clutch enables lighter upshifts and smooths out any hard downshifts.
The CB500F, like its 500cc stablemates, is homologated for EURO5, which from January 1st 2020,introduced significantly stricter engine emissions standards compared to EURO4. These requirements include substantial reductions in permitted carbon monoxide emissions, an over 40% decrease in total hydrocarbon emissions, tougher misfire detection and the introduction of a particulate matter limit.

1. Introduction
The CB500X – originally launched in 2013 alongside the naked CB500F and fully-faired CBR500R – brings crossover adventure style to Honda’s fun-focussed twin-cylinder ‘light middleweight’ trio. It is a motorcycle that, without fanfare, quietly gets on with the job of being supremely competent and adaptable in use for a wide variety of owners.
The CB500X’s usefulness is down to a straightforward equation – a perky, well-regarded twin-cylinder engine which produces real torque and drive from low rpm, and revs hard up top – plus a chassis that gives a supremely comfortable ride both around town and out on the open highway.
It slips between the role of short-hop commuter to weekend tourer effortlessly. Long travel suspension irons out irregular road surfaces, wide handlebars provide leverage and the upright riding position offers both comfort and a wide field of view for the rider. In other words, the CB500X has proved an all-rounder in every sense of the term.
In 2016, a first upgrade saw the CB500X receive a larger fuel tank, more wind protection and a taller screen. It also gained LED lighting, spring preload-adjustable front forks and an adjustable brake lever.
Its 2019 evolution delivered more sophisticated adventure style, more engine performance and a number of chassis upgrades, ensuring that while the CB500X remained confident in its wide-ranging abilities, its ‘X’ factor was amplified a good deal louder.
2. Model Overview
From urban commuter to weekend explorer, the CB500X is ready for anything. Its styling has a sharp adventure edge, and is complemented by long travel suspension, high-specification single-tube shock absorber, comfortable rider ergonomics and a 19-inch front wheel.
The CB500X’s 35kW engine is A2 licence-compatible and benefits from the 2019 upgrades to the inlet, exhaust and valve timing, which added 4% more power and torque between 3-7,000rpm compared to the previous model, and were accompanied by an enhanced exhaust note and a new assist/slipper clutch.
LCD instruments include a Shift Up and Gear Position indicator, and all the lighting is LED.
3. Key Features
3.1 Styling & Chassis
- Strong, tough adventure styling
- Tapered handlebars and wide steering lock
- Long travel suspension and 19-inch front wheel
- LCD instrument display with Gear Position and Shift Up Indicators
- Full LED lighting
For its 2019 evolution, the CB500X was reborn with a much more aggressive, ‘ready for the wild’ adventure style. Honda’s development engineers extended the radiator shrouds and fairing, with substantive new angles giving a strong three-dimensional texture and feel; new side covers interlocked with the fuel tank, cohesively linking the front and rear of the machine.
But the 2019 redesign was about much more than looks. Thanks to improved aerodynamic performance, the high-pressure air flowing around the fairing and screen was reduced, improving wind protection for the rider at highway speeds. The seat profile, too, was slimmed by shaving the shoulders at the front, allowing for easy movement around the machine, and aiding the already comfortable ground reach. To help the CB500X’s manoeuvrability the steering angle was increased 3° to 38° from centred to full lock, and the addition of a gunmetal grey tapered steel handlebar elevated control still further.
LCD instruments – set in a multi-surfaced and textured surround, echoing the overall design theme – feature a Gear Position and Shift Up indicator; this is set to a default 8,750rpm but can be adjusted in 250rpm increments between 5-8,750rpm. The tubular screen stay can also mount a GPS above the instruments.
The 35mm diameter steel diamond-tube mainframe is light and strong, with a tuned degree of yield that gives plenty of feedback to the rider as road surfaces change. The shape and position of the engine mounts, plus the frame’s rigidity balance, reduce vibration.
Wheelbase is 1445mm and rake and trail are set at 27.5 degrees and 108mm giving nimble, yet confidence-inspiring steering. Mass centralisation, with the engine in close proximity to the swingarm pivot point, delivers turning agility and optimum front/rear weight distribution ensures stability. Kerb weight is197kg.
Seat height is 830mm; overall dimensions are 2155mm x 825mm x 1410mm, with 180mm ground clearance. The fuel tank holds 17.5L including reserve, and, combined with the engine’s excellent fuel economy of 27.8km/l (WMTC mode), gives a range of 480km (over 300 miles).
The 41mm preload-adjustable telescopic front fork features 150mm of travel, with rear wheel travel of 135mm. A single-tube rear shock absorber (as found on larger capacity sports bikes) with its large-diameter piston ensures excellent suspension response and temperature management.
The CB500X has 9-stage spring preload adjustment working through a rigid box-section steel swingarm, which features pressed steel chain adjustment end-pieces. Final drive is via sealed 520 chain.
The 19-inch front wheel – along with the long travel suspension – ensures confident, supremely stable handling on rough surfaces. The lightweight aluminium rim wears a 110/80-R19 trail-pattern tyre, the 17-inch rear a 160/60-R17 tyre. A single front 310mm wave-pattern disc and two-piston brake caliper is matched to a 240mm rear disc and single-piston caliper. ABS is fitted as standard.
The 21YM CB500X will be available in three new colour and graphic schemes, each featuring a striking red rear sub frame, in tribute to the CRF1100L Africa Twin:
Grand Prix Red
Matt Gunpowder Black Metallic
Pearl Metalloid White
3.2 Engine
- Lively twin-cylinder power plant’s internal architecture mirrors that of the 2019 CBR1000RR Fireblade
- · Usable power and torque across the range
- Sportier sound from the dual-exit muffler
- Assist/slipper clutch eases upshifts and manages downshifts
- Homologated for EURO5
The CB500X’s A2-licence friendly, 8-valve liquid-cooled parallel twin-cylinder layout offers a well-proportioned balance of physical size and willing, enjoyable power output, with an energetic, high-revving character and zappy top end.
Already strong off the bottom, the 2019 engine upgrades saw faster acceleration through a boost in low-to-mid-range power and torque in the 3-7,000rpm range; with a 4% improvement coming via altered valve timing – with ‘close’ timing accelerated by 5° – and lift increased by 0.3mm to 7.8mm.
Feeding the PGM-FI fuel injection is a more-or-less straight shot of airflow through the airbox and throttle bodies – the 2019 upgrade saw the battery re-positioned further away from the rear of the airbox intake duct to allow greater airflow. The exhaust muffler features dual exit pipes, giving a sporty sounding edge to each pulse. Peak power of 35kW arrives at 8,500rpm, with 43Nm torque delivered at 7,000rpm.
Bore and stroke is set at 67mm x 66.8mm and compression ratio is 10.7:1; the crankshaft pins are phased at 180° and a primary couple-balancer sits behind the cylinders, close to the bike’s centre of gravity. The primary and balancer gears use scissor gears, reducing noise. The crank counterweight is specifically shaped for couple-balance and its light weight allows the engine to spin freely, with reduced inertia.
Acting as a stressed member, the engine complements the frame’s rigidity with four frame hangers on the cylinder head. Internally the cylinder head uses roller rocker arms; shim-type valve adjustment keeps weight down, for lower valve-spring load and reduced friction.
A silent (SV Chain) cam chain has the surface of its pins treated with Vanadium, reducing friction with increased protection against wear. Inlet valve diameter is 26.0mm with exhaust valve diameter of 21.5mm.
The piston shape is based upon those used in the 2019 CBR1000RR Fireblade to reduce piston ‘noise’ at high rpm. Friction is reduced by striations on the piston skirt (a finish that increases surface area, introducing gaps in which oil can flow for better lubrication). As with the CBR1000RR, an AB 1 salt bath process, used after isonite nitriding, forms a protective oxidisation membrane.
The ‘triangle’ proportion of crankshaft, main shaft and countershaft is very similar to that of Honda’s four-cylinder RR engines and much of the internal structure and engineering is taken directly from the 2019 CBR1000RR.
The crankcase uses centrifugally cast thin-walled sleeves; their internal design reduces the ‘pumping’ losses that can occur with a 180° phased firing order. The oil pump features improved aeration performance, with reduced friction; a deep sump reduces oil movement under hard cornering and braking. Oil capacity is 3.2L.
The CB500X’s six-speed gearbox is very close to that of its RR cousin and uses the same gear change arm structure and link mechanism. Introduced in 2019, an assist/slipper clutch enables lighter upshifts and smooths out any hard downshifts.
The 21YM CB500X, like its 500cc stablemates, is homologated for EURO5, which from January 1st 2020 introduced significantly stricter engine emissions standards compared to EURO4. These requirements include substantial reductions in permitted carbon monoxide emissions, an over 40% decrease in total hydrocarbon emissions, tougher misfire detection and the introduction of a particulate matter limit.

21YM HONDA CBR500R
Model updates: Following a ground-up redesign in 2019 that gave Honda’s A2-compatible ‘pocket rocket’ an aggressive, aerodynamically-driven sports makeover. For 2020 it is homologated for EURO5.

1. Introduction
Fast, frugal, affordable and fun, Honda’s fully-faired CBR500R – launched in 2013 alongside the naked CB500F and adventure-styled CB500X – gives a genuine sporting energy to its twin-cylinder ‘light middleweight’ trio.
Popular with riders looking to move up from a smaller machine, it instils the excitement of sports bike ownership into every ride yet also delivers sensible running costs, making it a great bike to both commute through the working week and enjoy at the weekend. It has also found favour with experienced riders looking to downsize their machinery while still experiencing the essence of enjoyable motorcycling.
In 2016, the CBR500R assumed sharper styling and LED lighting to go with upgrades to its front suspension; in 2019 it got an even more aggressive makeover, with a new form and riding position that outlined a keener sporting intent. Upgrades were also applied to the engine, to deliver stronger performance off the bottom, a strong surge through the rev range to the redline, and a more distinctive howling note.
2. Model Overview
Contrasting angles and shaping – between the very slim and more muscular – from the fairing nose to the seat unit outline the CBR500R’s look. It’s an ergonomic design for the rider to use aggressively which also features excellent aero management. Clip-on handlebars mount below the revised top yoke and the riding position is canted further forward compared to its two CB500 siblings.
The CBR500R’s 35kW engine is A2 licence-compatible and benefits from the 2019 upgrades to the inlet, exhaust and valve timing, which added 4% more power and torque between 3-7,000rpm compared to the previous model, and were accompanied by an enhanced exhaust note and a new assist/slipper clutch.
LCD instruments feature a Shift Up and Gear Position function and all the lighting is LED.
3. Key Features
3.1 Styling & Chassis
- Aggressive lines with purposeful, dual LED headlights
- Aerodynamically efficient and ergonomically comfortable
- Clip-on handlebars give a sporty riding position
- LCD instrument display, with Gear Position and Shift Up indicators
- Full LED lighting
For its 2019 evolution the CBR500R’s fully faired form was made more aggressive with straight, wedge-like feature lines and extended lower fairings that emphasise a real sense of speed. The rider’s seat pad and seat unit – plus the upper and side fairings – were narrowed to improve ergonomics and movement. Sharply-chiselled dual LED headlights stare menacingly ahead, matching the LED indicators.
The view forward, from the CBR500R’s cockpit, is pure sports. The handlebars clip on beneath the sporty top yoke and as a result the riding position is unmistakably ‘sportsbike’; the fairing is also set low, to give the rider the control and stability for which Honda sports bikes have long been famed.
LCD instruments feature a Gear Position and Shift Up indicator; this is set to a default 8,750rpm but can be adjusted in 250rpm increments between 5-8,750rpm
The 35mm diameter steel diamond-tube mainframe is both light and strong, with a tuned degree of yield that gives plenty of feedback to the rider as road surfaces change. The shape and position of the engine mounts, plus the frame’s rigidity balance also reduces vibration.
Wheelbase is 1410mm and rake and trail are set at 25.5°/102mm giving nimble, yet confidence-inspiring steering. Mass centralisation, with the engine in close proximity to the swingarm pivot point, delivers turning agility and optimum front/rear weight distribution ensures stability. Kerb weight is 192kg.
Seat height is low at 785mm, making the CBR500R very easy to manage and its riding position comfortably accommodates riders of any height. Overall dimensions are 2080mm x 755mm x 1145mm, with 130mm ground clearance. The fuel tank holds 17.1L, including reserve and combined with the engine’s excellent fuel economy gives a range of 480km (over 260 miles).
The 41mm telescopic front fork, with 120mm stroke, delivers a compliant yet controlled ride and gives great feel for front tyre grip. The single-tube rear shock absorber (as found on larger capacity sports bikes) with its large-diameter piston ensures excellent suspension response and temperature management. It has 9-stage spring preload adjustment and works through a rigid box-section steel swingarm, which features pressed steel chain adjustment end-pieces. Final drive is via sealed 520 chain.
Lightweight, 17-inch cast aluminium wheels employ hollow cross-section Y-shaped spokes. Front wheel width is 3.5inch with a 120/70-ZR17 tyre, the rear 4.5inch with a 160/60-ZR17 tyre. A single front 320mm wavy disc and two-piston brake caliper is matched to a 240mm rear disc and single-piston caliper. ABS is fitted as standard.
The CBR500R will be available in the following colour options:
Matt Axis Grey Metallic
Grand Prix Red
Pearl Metalloid White
3.2 Engine
- Lively twin-cylinder power plant’s internal architecture mirrors that of the 2019 CBR1000RR Fireblade
- · Usable power and torque across the range
- Sporty sound from the dual-exit muffler
- Assist/Slipper clutch eases upshifts and manages downshifts
- Homologated for EURO5
The CBR500R’s A2-licence friendly, 8-valve liquid-cooled parallel twin-cylinder layout offers a well-proportioned balance of physical size and willing, enjoyable power output, with an energetic, high-revving character and zappy top end.
Already strong off the bottom, the 2019 engine upgrades saw faster acceleration through a boost in low-to-mid-range power and torque in the 3-7,000rpm range; with a 4% improvement coming via altered valve timing – with ‘close’ timing accelerated by 5° – and lift increased by 0.3mm to 7.8mm.

HONDA REACHES TEN YEARS OF PRODUCTION OF DUAL CLUTCH TRANSMISSION TECHNOLOGY FOR MOTORCYCLES
- Honda’s landmark – and still unique – technology first appeared in dealerships across Europe in 2010
- Over 140,000 motorcycles equipped with Dual Clutch Transmission (DCT) have been sold in Europe
- This ‘easy and direct’ technology has been available on ten Honda models in Europe since its introduction
The original VFR1200F and Honda’s current DCT line-up The evolution of DCT
Honda is marking a decade since its Dual Clutch Transmission (DCT) technology first appeared in its two-wheeled product line-up.
Having first appeared in dealerships across Europe on the VFR1200F sports tourer, Honda’s DCT remains unique in the world of powered two-wheelers. In total, over 140,000 machines with DCT have been sold in Europe, and in 2019, 45% of Africa Twins, 52% of NC750X’s and 67% of Gold Wings sold in Europe were the DCT version.
Its success has been in large part due to a constant evolution of the technology, with refinements to the smoothness and timing of the gear shifts, and adaptations to match the riding characteristics required of a broad range of different models. Examples include an off-road focussed ‘G switch’ addition for the Africa Twin and X-ADV, and synchronisation with Hill Start Assist, Walking Mode and Idling Stop on the flagship GL1800 Gold Wing luxury tourer.
INTERVIEW WITH DUAL CLUTCH TRANSMISSION CHIEF ENGINEER MR. DAI ARAI
Dai Arai joined Honda in 1999 and has been a driving force behind Honda’s unique Dual Clutch Transmission for ten years.
This Q&A gives an insight into his background, his life in motorcycling and in Honda, and the challenges faced over a decade of developing DCT for bikes.
On ten years with DCT…
What is the origin of DCT?
Before my time at Honda, there were other automatic transmissions such as the ‘Hondamatic’ gearbox in the 1970s which relied on a torque converter, and the Human Friendly Transmission on the DN01.
So before the VFR1200F came with the first DCT, the idea of making an automatic transmission was around for many years.
The big difference with DCT is that it involves much less losses than the previous systems, so it gives a much more direct and sporty feeling.
What was the hardest problem to solve?
Everything on the development of the very first DCT for the VFR1200F was a real struggle.
No-one had ever done it before, so it was so difficult from both the hardware and software point of view. It was really the first time transmission engineers had been involved in electronic controls.
With the hardware, we had to develop a crankshaft case that could be used for both DCT and manual transmission engines, to allow us to prepare MT and DCT variants in the same frame. So we used two mainshafts with one inside the other to keep the package compact. Giving that small package the required strength and durability was a big challenge.
There was also the challenge of reducing the noise of the gear shift. Because the gear mechanism itself is the same as a manual bike, the DCT makes the exact same ‘pre-engagement’ noise from the gear dogs as on a manual shift. For some riders, hearing this shifting sound in automatic modes without the normal ‘manual’ inputs into a gear change could sound strange, so reducing that sound was a big extra challenge.
On the software side, programming the gear shift schedules for this new kind of technology was a real challenge. No-one had attempted to make such a system, and it takes thousands of hours to come up with the right programmes for the shift schedules.
What do you think had been the biggest single improvement throughout the decade of DCT?
It’s not possible to pinpoint one particular change as most important. That’s because the system has been evolved consistently over the decade, with different changes being introduced that not only improved DCT itself, but also made it bring out more and more the different riding characteristics required of each different model.
One of the first big steps was the automatic return to Automatic mode if you used the manual triggers as an override to select a gear. It’s a lot of programming to make the return to automatic as intuitive as possible, because you have to calculate the riding situation and therefore the rider’s intention – was it a downshift coming into a tight corner, a downshift to overtake on a straight road, etc. It’s not just a question of returning the system to Automatic after a certain number of seconds.
Later, we refined the way that the throttle ‘blip’s on the downshift to accurately match the revs and make those shifts really smooth. These changes involved a lot of synchronization with the PGM-FI fuel injection controls.
We also introduced the ‘Adaptive Clutch Capability Control’ which uses the electronic control of the DCT system to ‘slip’ the clutch a little when the throttle position is changed initially from a fully closed or fully opened position. That really helped smooth out the bike behaviour.
On the other hand, the ‘G’ switch introduced on the CRF1000L Africa Twin and later the X-ADV reduces the amount of clutch slip to give a more direct feeling for rear wheel traction. Especially off-road, this can allow riders to do controlled slides.
We’ve also linked the system with riding modes thanks to Throttle by Wire on the Gold Wing, which also helps to shorten the shifting time.
And on the latest CRF1100L Africa Twin, linking with the IMU really helps refine the gear shift timing through corners, as the IMU gives definitive information about lean angle.
So the system has developed continuously, and will continue to do so. That’s one of its great advantages – it can be continuously improved.
How would you personally describe the benefits of DCT?
The biggest thing for me is how much brain ‘bandwidth’ it frees up to use on what is most enjoyable about riding – cornering, looking for the right lines, timing your braking and acceleration.
The other things is that it is both easy and direct. ‘Easy’ meaning no need to use a clutch in slow traffic, no chance of stalling, no bashing helmets with a pillion. ‘Direct’ being the speed of the gear change, the ability to use the triggers, and, as I mentioned, to concentrate purely on your riding.
What would you like to see as the next application for DCT?
Personally, I’d love to see DCT on our Dakar Rally bike. That kind of riding – where fatigue is possible, and concentration so important – means the system has a big benefit.
Off-road, people are often surprised at how much DCT can help them – working a clutch lever standing up is not so easy, and uses up a lot of energy and concentration. Also, of course, with DCT the rider cannot stall in difficult situations.
How is control differentiated model by model?
Mainly, the different programmes for the shift timing. Each model is different. For example, the shift pattern on the X-ADV is much sportier than on the Integra, as it upshifts at higher rpm and downshifts also at higher rpm for more engine braking.
Every single DCT model is programmed with a different shift timing pattern to add character and taste in the riding feel.
What would your message be to riders who don’t think DCT is for them?
Please give it a try. It may take a short time to become used to it, but it really opens up new possibilities in your riding.
Arai-san’s life with Honda and motorcycles…
What was your ambition when you were young?
I wanted to be a Formula One mechanic. Formula One was really big in Japan when I was at high school, with drivers like Ayrton Senna and Satoru Nakajima massively popular and I thought it would be cool to be one of the mechanics in the pit lane.
What did you study?
Mechanical Engineering.
I branched out into studying more about control software and human-to-machine communication – we made robots that did ‘kendo’ by remote control as part of our research (kendo = Japanese fencing). This involved designing parts of the robot and the control systems. This experience helped me once I got into Honda.
What is your biggest source of motivation?
I want to understand the language of machines… what are they telling us?
When I was young, I used to love taking things apart and putting them back together… I did all the maintenance work on my own bicycles, fixed CD players, and replaced parts on amplifiers to get the best sound possible. Even now, I have this personality where I can’t just ignore it if there is any problem or issue with a machine. When I’m riding, if there is any sound or feeling from a bike which makes me think there’s something wrong, I have to stop and try to figure out the root cause and how to fix it. I can never just ‘ride around a problem’.
What was the first bike you bought?
A CRM250R. It was the most powerful bike I could afford at the time, but I really wanted a VFR400R.
I had got my licence without telling my parents. When I told them ‘I’m buying a bike’, they said ‘What about getting a licence first?’. So I told them, ‘No problem. I already have one!’.
What are your current bikes?
A 1991 XR250R, a 1982 Monkey and a 2001 Ducati Monster 750.
Which bike do you wish you still owned and why?
My VTR1000F. My wife and I decided we had to sell one of our bikes, and my wife rides the Monster, so we decided to keep that one!
What is your dream bike?
I’d love to ride the 5 cylinder MotoGP bike – the RC211V. I’ve been lucky enough to ride a MotoGP bike when I was developing the quickshifter. And recently, I had an opportunity to ride a 1992 NR. That was amazing.
As I’m in charge of automatic transmission research, I’d also like to try the CB750 EARA Hondamatic and the Juno with the Badalini style transmission.
What is your greatest biking achievement?
One of the best touring rides I did was to the north of Japan two-up with my girlfriend at that time. I made a bespoke rear carrier for the CRM250R and put all our camping gear on it. At the time, you weren’t allowed a pillion on the highway, so it was backroads all the way for a four to five day trip. In the end the rear suspension started making a strange noise and broke!
Eventually, my girlfriend got her bike licence and became my wife. My greatest achievement through biking!
What sort of riding do you do in your spare time?
I commute on the Ducati Monster, and the two Honda’s for shopping.
What is your speciality – frame, engine, styling?
Transmission research.
What projects have you worked on at Honda?
Most of the DCT bikes since the first VFR1200F. Work on the quickshifter for the Fireblade. And several ATV and Side-by-Side models.
If you could get the chance to design any type of bike regardless of cost or regulations, what would it be?
A kind of up-to-date CRM250R– over the years I’ve come to enjoy smaller bikes more and I would like something like the XR that I have but with more punch.
Who was the most influential person on your career and why?
Soichiro Honda. I was especially influenced by the book he wrote about his outlook on life. He seemed to have a character that would light up a room and brighten up people around him and I consciously try to be as cheerful as possible at work.
What is your favourite sport?
Athletics. 400 metres was my event.
What is your favourite country?
Japan and Italy.
What is your favourite book?
Books on Japanese history – the samurai age.
What is your favourite film?
Cinema Paradiso.
What is your favourite food?
Gyoza (a Japanese dumpling).
Mac or PC?
PC.
Beer, sake, wine or…?
Japanese sake, German beer.
MotoGP, WorldSBK or…?
MotoGP.
Who was your biking hero?
Tadayuki Okada. He was a pioneer for Japanese riders in his day.
All the petrol in the world has run out. You have the last 10 litres in the world. What do you do?
Give it to someone else and work on creating a world that doesn’t rely on petrol.
THE HONDA AFRICA TWIN HEADS TO ICELAND FOR THE THIRD ADVENTURE ROADS TOUR
- Adventure Roads heads to Iceland for 2021
- 30 riders all on the latest CRF1100L Africa Twins
- 11 days
- Once in a lifetime experience, complete ‘turn-key’ package
- Meet and benefit from the knowledge of HRC rally stars
Following in the wheel tracks of previous tours across Norway and South Africa, Honda’s Adventure Roads returns for its third edition in June 2021 to tackle the unique volcanic landscape of Iceland on the CRF1100L Africa Twin.
The first Adventure Roads trip saw 40 motorcycle enthusiasts set out in summer 2017 on an 8-day, 3,500km journey from Oslo to Nordkapp – the northernmost point of Europe. Returning in 2019, Adventure Roads travelled 3,700km ‘coast to coast’ from Durban to Cape Town in South Africa, exploring varied terrain and epic landscapes over 12 adventure filled days.
For 2021, Honda Motor Europe will be offering 30 riders the opportunity to ride the new CRF1100L Africa Twin, the CRF1100L Adventure Sports as well as the CRF1100L Adventure Sports ES – complete with Showa EERA semi active suspension – on a once in a lifetime 11 day journey through the land of ‘Fire and Ice’.
From Reykjavik, the most northerly capital city in the world, the third Adventure Roads tour will wind its way down to the south of the island, before heading through the remote highlands of the north, and back to Reykjavik. Taking in some of the most stimulating riding scenarios in the northern hemisphere, participants will guide their Africa Twins down perfect tarmac roads and gravel passes, navigate the famed black sand, and ford rivers, all while taking in the majestic beauty of an island famed for its volcanos, waterfalls, lava fields, geysers and 22hrs+ of summer daylight.
‘Adventure Roads 2021’ will be a turn-key package for 30 customers from across Europe. With all accommodation, Africa Twins, guides and maintenance taken care of, the participants will arrive safe in the knowledge that they can relax, ride and enjoy. And get to meet and benefit from the riding tips of some of Honda’s HRC rally stars.

The Honda CB1000R, flagship of the Neo Sports Café range, has proven itself to be the perfect canvas for custom builders across Europe.
Honda are revisiting 12 of the continent’s best customised CB1000Rs, first shown last year at the Wheel & Waves festival in Biarritz, with a webpage giving users the chance to chair their own judging panel and ‘drag and drop’ the bikes in their order of preference from one to twelve. Having made their selection, users will be able to share their choice with friends via Facebook™, Twitter™ or WhatsApp™ .
Among the twelve CB1000Rs at www.hondacustoms.com are the Africa Twin-inspired ‘CRF1000 Africa Four’, the Monkey bike homage ‘Monkey Kong’ and the ‘Alfredo’ tribute to classic Freddie Spencer CBs of yesteryear. All twelve certainly merit a close inspection.
The Honda Customs page is available in English, French, German, Italian and Spanish and once users have chosen their favourites, they’ll be able to download their number one choice as either a desktop or mobile phone wallpaper.
