Honda CRF 1100L Africa Twin / DCT

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.

 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.

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.

 Key Features

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

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.

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.

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.

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.

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.
