The CRF450R’s technical updates include a narrower intake-port shape and longer intake funnel, revised cam profile and smaller HRC developed 44mm throttle body diameter, resulting in smooth power delivery and increased torque at low rpm, reducing fatigue and improving acceleration out of corners.

The frame’s rigidity has been optimised by increasing material thickness in strategic locations and the use of steel engine mounts (replacing aluminum) helps improve front-end traction. Engine hangers changed from aluminum to steel. A higher-rate shock spring and revised fork settings complement the rigidity-optimised frame and updated shock mounts, allowing the suspension components to move more freely and avoid binding. The result is increased tyre grip and improved stability and bump absorption, making the bike more stable and delivering faster turns.

Front and rear suspensions are fully adjustable. The rear shock has 11 positions for rebound and 6 for compression, while the 49mm USD coil spring fork has 13 positions for rebound and 15 for compression.

To enhance strength and reduce noise, the muffler body is now constructed from heat treated aluminum, and much more resistant to impact.

Black D.I.D wheels deliver durable performance while looking great. Petal-style brake rotors disperse heat, and a low-expansion front brake hose gives strong feel and consistent stopping power. The CRF450R comes standard with Dunlop Geomax MX33 tyres, developed with the help of top motocross pros, and featuring technologies that deliver superior grip, slide control, bump absorption and durability

The standard electronics package include 3-mode Honda Selectable Torque Control (HSTC), 3-mode HRC Launch Control and 3-mode Engine Mode Select Button (EMSB) mounted on the handlebar.

HSTC works to minimise rear wheel spin (thus reducing wasted forward drive) and maximise traction. “Mode 1” intervenes most lightly, and after the longest time – useful for reducing wheelspin and maintaining control in tight corners. “Mode 3” has the system intervene more quickly and strongly, and is therefore useful in more slippery, muddy conditions. “Mode 2” naturally offers a mid-point between 1 and 3 in terms of speed and strength of intervention. The system can also be switched off completely.

HRC Launch Control gives any rider the best option for a strong start and also has 3 modes to choose from: “Level 3” (8,250rpm), for muddy conditions or “novice”; “Level 2” (8,500rpm), for dry conditions or “standard”; and “Level 1” (9,500rpm), for dry conditions or “expert”.

The Engine Mode Select Button (EMSB) alters the engine’s character and 3 maps are available to suit riding conditions or rider preference: “Mode 1 – Standard”, “Mode 2 – Smooth”, and “Mode 3 – Aggressive”.
