1. Introduction

It’s been well over three decades since the Honda XRV650 Africa Twin first rolled into Europe and while the motorcycle that now bears its name – launched in 16YM as the CRF1000L Africa Twin – was a brand-new motorcycle 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 light 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, with over 85,000 units bearing the ‘Africa Twin’ name sold since its return.

18YM saw the Africa Twin, in both manual transmission and Dual Clutch Transmission (DCT) form, receive Throttle By Wire (TBW) control plus 4 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 CRF1100L 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 off-road territory.

For 20YM, the introduction of a bigger capacity, longer stroke 1084cc engine marked another landmark in the evolution of the Africa Twin. The CRF1100L Africa Twin* itself was comprehensively redrawn with an aggressive, compact rally style and even sharper off-road focus. Meanwhile, the touring comfort, technology and ability of the CRF1100L Africa Twin Adventure Sports were also further enhanced – including the option of cutting-edge Showa Electronically Equipped Ride Adjustment (Showa EERA^™) suspension.

The 22YM Africa Twin Adventure was equipped with refined DCT settings for even smoother handling in 1^st and 2^nd gears, plus a new, more compact screen design and striking ultra-modern ‘Cracked Terrain’ graphics.

24YM marks another major update for the CRF1100L Africa Twin Adventure Sports. Updated chassis dynamics based around a new 19in front wheel, more power and torque for the engine, further DCT refinements and a more muscular new look move the model on yet again.

2. Model Overview

The 24YM CRF1100L Africa Twin Adventure Sports shares the frame and engine of the more off-road focussed CRF1100L Africa Twin but has a role very much of its own: to offer riders real continent-crossing long-haul ability and practicality both on and off-road.

For 24YM Showa EERA^™ offers optimum constantly-adjusted damping control. Four default modes – SOFT, MID, HARD and OFF-ROAD – cover every type of riding situation, and there’s a USER mode for further fine-tuning on the move. Rear spring preload can also now be adjusted while moving.

24YM also sees the adoption of a 19-inch front wheel (as opposed to 21-inch) wearing a wider 110/80-19 tyre (from 90/90-21). This setup gives more front tyre grip and feedback for better on-road stability and comfort when fully loaded. The seat has a revised cushion thickness for enhanced comfort and is set lower, at 835/855mm. Suspension stroke, front and rear, is reduced to 210/200mm, also for improved on-road handling ability and confident ground reach.

To boost acceleration, especially for when two-up and fully loaded, the 1,084cc parallel twin cylinder engine has been tuned – via intake, combustion and exhaust development – to produce more low- and mid-range torque, with 112Nm at peak and no loss of power, which remains 75kW.

Long-range touring credentials come in the shape of a large 24.8L fuel tank, extensive wind protection (from both the redesigned upper fairing and fairing side panels), 5-way height-adjustable screen, large engine sump guard, aluminium rear carrier plus tubeless wheels and tyres. ACC charger and heated grips are also standard fit.

DCT has been refined for more natural feel from initial pull-away and at very low speeds. A six-axis Inertial Measurement Unit (IMU) controls 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. There are four default riding modes: URBAN, TOUR, GRAVEL and OFF-ROAD.

Tailored for complete control, the riding position features a slim section seat, featuring an increased cushion thickness for added comfort and high-set handlebars. Dual LED Daytime Running Lights (DRL) feature three-stage Cornering Lights that automatically adjust the field of illumination depending on the lean angle, giving optimum visibility for improved safety. Cruise control and heated grips are standard-fit. A full colour Multi Information Display (MID) 6.5-inch TFT touch screen brings immersive engagement with the machine’s systems, plus Apple CarPlay^®, Android Auto^® and Bluetooth connectivity.

For 24YM the CRF1100L Africa Twin Adventure Sports will be available in the following paint options, that both feature bold big logo graphics.

3 Key Features

3.1 Chassis

• Showa Electronically Equipped Ride Adjustment (Showa EERA^™) suspension as standard
• New 19-inch front wheel mounts a 110/80-19 tyre for improved road handling
• Lightweight frame, with bolt-on aluminium subframe and light, rigid CRF450R-style swingarm for outstanding rear wheel traction and feel
• Six-axis Bosch IMU control; cornering ABS provides sure-footed braking and features an off-road setting

Showa Electronically Equipped Ride Adjustment (Showa EERA^™ ) suspension was an option for the previous CRF1100L Africa Twin Adventure Sports. Now, for 24YM it is standard fit.

The system automatically provides optimum damping force relative to the stroke speed. It works by adjusting the damping level based on information from three sources: bike speed (from the ECU), the bike’s stance and attitude (from the Inertial Measurement Unit) and the fork behaviour (from the stroke sensor). The Suspension Control Unit makes adjustments to suspension behaviour within a mere 15 milliseconds (0.015 seconds) of these calculations being made.

The system’s flexibility means that damping adjustment can be programmed to change as the vehicle speed changes – allowing firmer damping at higher speeds, for example. In addition, it can adapt to specific circumstances such as ‘preparing’ the bike’s suspension for landing from a jump, or reducing ‘dive’ under hard braking.

Quite simply, the Showa EERA^™ suspension means the rider can select low-speed ride comfort, high speed stability, sporting on-road performance and off-road response at the touch of the screen.

Five suspension modes are available:

MID sits between hard and soft, for easy handling in a wide range of situations. It is automatically selected with Urban riding mode.

HARD is stable, responsive and the firmest damping for two-up and fully laden touring. It is automatically selected with Tour riding mode.

SOFT offers a comfortable, secure ride on poor roads with lowest damping force. It is automatically selected with Gravel riding mode.

OFF-ROAD gives optimum dirt performance, with gradually increasing fork damping relative to stroke speed and firmer all-round rear shock damping. It is automatically selected with Off-road riding mode.

Whereas the above suspension settings are automatically selected according to the riding mode, in USER Riding Mode, the rider can adjust spring preload finely, through 24 steps, front and rear.

The new 19-inch front wheel mounts a 110/80-19 tyre (a change from the previous 90/90-21 item), and the rear a 150/70-18 improving front grip, comfort and stability in both sporty solo riding and two-up touring. Suspension stroke has also, naturally, been reduced, front and rear, to 210/200mm (from 230mm/220mm) to match the upgraded road handling dynamic of the new front wheel and tyre. The reduction lowers the centre of gravity and improves both slow-speed manoeuvrability and ground reach.

The design of the steel semi-double cradle frame balances off-road ability with excellent, all-round on-road manners. Rigidity around the steering head is optimised to enhance feel for front end grip; the main spars are slim and straight with no front cross pipe. A bolt-on aluminium subframe saves weight.

Ground clearance is 220mm (30mm less than CRF1100L Africa Twin), with wheelbase of 1550mm and rake and trail of 27.5° /106mm (from 1574mm/27.5°/113mm). Wet weight is 243kg (253kg for the DCT option).

The lightweight aluminium swingarm – taking its direction from the design used by the CRF450R – maximises rear wheel traction and rider feel. 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.

At the very heart of the bike’s all-round 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 aids the management of rear wheel traction via TBW and HSTC, and front wheel lift through Wheelie Control. It is also integral to the functioning of the EERA^TM suspension.

Cornering ABS (which features revised 24YM settings to match the new front wheel and suspension setup) is also managed via the IMU, which 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. Likewise, if it detects sudden rear wheel lift, it finely controls brake force to maintain stability.

There is an off-road ABS setting and, when stationary the rear ABS can be turned off completely for off-road riding if required.

Up front, compact two-piece radial-mount four-piston calipers work dual 310mm ‘wavy’ floating discs through sintered pads. The rear 256mm ‘wavy’ disc features hole punching and shaping for optimal rear wheel control.

19 inch front and 18 inch rear (stainless steel) spoked wheels wear 110/80R19M/C 59V and 150/70-R18M/C 70H – now tubeless rather than tubed, which allow for easier repairs without the need to remove the wheel. Bridgestone Battlax Adventure A41 are approved as OEM tyres. Block pattern tyres (Michelin Anakee Wild 110/80R19M/C 59R TL and 150/70 18M/C 70R TL) are also approved for fitment.

3.2 Engine

• 1,084cc, twin-cylinder engine generates an extra 7% torque at 112Nm peak, with stronger power and torque in the low to mid-rpm range
• Compression ratio raised to 10.5:1, alongside development of ECU settings, valve timing, intake and exhaust
• Unicam 8-valve head, semi-dry sump and slipper clutch

The 1,084cc, 8-valve parallel-twin engine produces 75kW @ 7,500rpm (as before) with peak torque increasing to 112Nm @ 5,500rpm (up from 105Nm @ 6,250rpm). Bore remains 92mm with 81.5mm stroke; compression ratio is now 10.5:1 (from 10.1:1). There are significant gains in output of both power – and especially torque – off the bottom and through the middle of the rev-range when compared to the previous model.

CRF1100L Africa Twin Adventure Sports Power and Torque comparison

The airbox intake ducts go from 29mm diameter to 35mm, to draw in more air, while the two internal trumpets that feed air from the airbox are both an extra 65mm longer. 46mm throttle bodies feed the inlet ports and the bore and cylinder pitches are aligned to create a smooth air intake profile. There are new, optimised ECU settings and the injector angle delivers a direct spray into the 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 and entire engine package; inlet valves are 10.1mm in diameter, exhaust valves 9.3mm. Valve timing has been revised to match the engine’s new tune. Aluminium cylinder sleeves save weight while the 270° phased crankshaft and uneven firing interval create the engine’s desirable signature ‘throb’ and character.

The crankcases are split horizontally; 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.

The engine features 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.

The aluminium clutch centre and pressure plate use ‘assist’ cams to ease upshifts and ‘slipper’ cams for deceleration and downshifting. The six-speed manual gearbox uses the same shift-cam design as found on the CRF450R to ensure positive changes.

The exhaust muffler has been updated internally to match the changes on the intake side and improve driveability. Lighter than the previous design its new internal structure delivers enhanced engine performance and gives a pleasing exhaust note ‘pulse’ at lower rpm. Another 24YM revision is a tune of the high-rpm sound for a more ‘bass’ filled note.

3.3 Engine & Chassis Management Electronics

• IMU-managed HSTC intervention levels have focus on off-road use
• Wheelie Control features 3 levels and IMU management
• Four riding modes: TOUR, URBAN, GRAVEL and OFF-ROAD
• Two USER modes allow for complete customisation

Throttle By Wire (TBW) management and a six-axis Inertial Measurement Unit (IMU) are at the heart of the electronic package. The system – updated for 24YM with refined feel – offers 4 levels of power and 3 levels of engine braking. There are seven levels of Honda Selectable Torque Control (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 is optimised to allow 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. 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. Like HSTC, 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 further 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 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.

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
• Updated for smoother, more natural feel when first moving away and at slow speed
• S mode (with 3 levels) revs higher and downshifts sooner than D, for more aggressive riding
• G Switch offers more feel for traction off-road
• Incline detection adapts shift pattern depending on gradient
• IMU allows corning detection function for improved shift timings

Honda has sold over 240,000 DCT-equipped motorcycles across Europe since the system first appeared as an option on the VFR1200F in 2009. Testament to its acceptance in the marketplace in 2023 DCT versions of Africa Twin Adventure Sport accounted for 71% of the model’s sales.

For 24YM, the CRF1100L Africa Twin Adventure Sports’ DCT has been developed to give a much more natural, ‘feathered’ clutch feel on initial take-off and between first and second gears. This has been achieved by improvements to the hydraulic control to equal better clutch response.

The system has been adjusted to make use of the engine’s increased torque, shifting down earlier. It also uses cornering detection – when the IMU recognises the bike is leant over it subtly adjusts the shifting programme for the most natural gear changes. This function has also been improved for 24YM.

DCT delivers consistent, super-fast seamless gear changes, and very quickly becomes second nature in use. It uses two clutches: one for start-up and 1^st, 3^rd and 5^th gears: the other for 2^nd, 4^th and 6^th, 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, with the ECU making the engine rev a little higher before shifting up, and shift 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 CRF1100L Africa Twin Adventure Sports ES 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.

3.5 Styling & Equipment

• New upper fairing adds muscular looks and improves wind protection
• Compact, height-adjustable screen 
• 8L fuel tank, aluminium insert panels, rear rack and engine bash plate
• Daytime Running Lights (DRL) with Cornering Lights
• Cruise control, heated grips and ACC charger
• Multi Information Display (MID) 6.5-inch TFT touch screen 
• Apple CarPlay^®and Android Auto^® allow use of a smartphone through the MID

Designed for the long-range ride, the 24YM CRF1100L Africa Twin Adventure Sports has an extensive front fairing, aggressively redesigned to improve upper body wind deflection and aerodynamics. It mounts a compact, 5-level height adjustable screen that opens up vision while still offering plenty of protection.

The seat too, is new and uses a +15mm thicker urethane foam cushion with optimised density to reduce long-distance riding fatigue, and 8% larger area. Tool-free height adjustment is 835 or 855. There is also a Low Seat accessory, which drops seat height down to 795/815mm.

Holding 24.8L, the fuel tank offers a potential range of over 500km, thanks to fuel economy of 4.9L/100km (20.5km/L) (WMTC mode). A large engine sump guard and aluminium rear carrier are included in the specification.

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. For additional security features three-stage Cornering Lights that use speed and lean angle (controlled by the IMU) automatically adjust the area illuminated when cornering. Large knuckle guards are standard fitment.

The full colour Multi Information Display (MID) 6.5-inch TFT touch screen keeps the rider in control, 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.

The MID incorporates Apple CarPlay® and Android Auto®, allowing use of a smartphone through the touchscreen. Navigation apps can also be accessed and displayed and, via a Bluetooth helmet headset, calls can be made or received. The smartphone itself plugs into a USB charging port on the right of the MID. Hands-free wireless Bluetooth connectivity is also an option and all control inputs are made from the left-hand switchgear.

The front and rear indicators have an Emergency Stop Signal (ESS) 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 and standard-fit cruise control eases long-distance highway travel.

A new high-performance, lightweight and compact lithium-ion battery is standard fit, contributing to mass centralisation.
