Honda CRF1100 A / A4 / D / D4 Africa Twin 2020-2023 Service Manual

Rider Magazine's own testing frames the genuine bump this generation represents: on the Jett Tuning dyno, "the new mill pumped out 92 horsepower at 7,600rpm (redline is 8,000) at the rear wheel and 69.5 lb-ft of torque at 6,300, an improvement that is quite noticeable throughout the powerband." That same review confirms the genuine sales momentum this platform had already built before this update: "today Honda says it has sold 87,000 units worldwide and that the Africa Twin is now the #2 best-selling liter-class adventure bike."

Power comes from a 1,084cc liquid-cooled parallel-twin, Unicam with 4 valves per cylinder, delivering a claimed 101 hp at 7,500 rpm and roughly 77 lb-ft (105 Nm) of torque at 6,250 rpm through a 6-speed transmission — Visordown's own technical breakdown details exactly how Honda got there: "to create the CRF1100L engine, Honda have kept the same basic architecture as before, dragging the stroke from 75.1mm to 81.5mm and keeping the bore at 92mm," an 86cc displacement increase paired with a new 43mm throttle body and reworked cylinder head. Honda's own 2020 launch materials confirm this wasn't just a bigger engine bolted into the old chassis: "an updated frame with optimized handling characteristics; a new, separate aluminum rear subframe; a new, CRF450R-style aluminum swingarm" all arrived alongside the displacement bump — genuine chassis-level rework, not a simple powertrain swap.

The model naming across this range (A/A4/D/D4) reflects Honda's genuine drivetrain and equipment split: the "D" designation covers DCT-equipped models (Honda's automatic Dual Clutch Transmission), while non-suffixed models retain a conventional manual clutch; the "4" suffix within either family typically denotes ABS or a specific market/equipment configuration. Honda's own 2020 launch confirms both the manual and DCT versions gained a genuine electronic safety-net upgrade: "a six-axis inertial measurement unit (IMU) makes possible the addition of wheelie control, cornering ABS, rear-lift control, DCT cornering detection and cornering lights" — real lean-angle-aware electronics that weren't present on the earlier CRF1000L generation. MCN's own review confirms the DCT gearbox specifically benefited from this IMU integration: "there is a DCT version, whose performance has been significantly upgraded through it being linked to the IMU, making it gradient and corner responsive in its gear selection." Wikipedia's own account confirms genuine running refinement across this exact span: 2021 brought Android Auto integration alongside the existing Apple CarPlay, "the DCT transmission received optimized first and second gears for smoother movement from a stop and at low speeds," and "the 2023 Africa Twin is unchanged except for new color options" — Matte Ballistic Black Metallic, Glint Wave Blue Metallic Tricolor, or the carryover Grand Prix Red, closing out this exact generation before Honda's 2024 update brought a further compression and torque increase. The Adventure Sports variant, per MCN's own detailed spec breakdown, adds a larger 24.8-litre tank, heated grips, cornering lights, a five-way adjustable screen, and — on the ES trim specifically — Showa's Electronically Equipped Ride Adjustment (EERA) semi-active suspension, genuine long-distance touring equipment layered onto the same fundamental 1,084cc platform shared with the more off-road-focused standard model.

This factory service manual covers the procedures, torque specs, and diagrams needed to keep a 2020-2023 CRF1100L Africa Twin A/A4/D/D4 running the way it was built to.
