With an HRC inspired engine, along with a seventh generation chassis, it’s a combination that packs a hefty punch from the start ’til the end of the day.
STRONGER FOR LONGER
Total control and superb handling for the expert Enduro rider.
Like its motocross cousin, the CRF450RX has been developed straight from AMA and European MX1 teams. The result is an improved power to weight ratio that makes the bike easier to ride over distance. It also comes with EMSB (Engine Mode Select Button) – three modes that you can adjust to suit the ride and the track. You’ll feel completely at one with the bike as it delivers high levels of feedback, stability and traction.

All the tough characteristics of the CRF450R, with three rider modes and larger fuel capacity for long distance Enduro racing. Comes with Digital CDI ignition and electric start.
Absolute holeshot, the CRF450R has a completely new engine, with three rider modes and a redesigned chassis, developed straight from AMA and European MX1 teams. The power to weight ratio has been improved for even better handling and comes with factory spec suspension, Digital CDI ignition and an optional electric start.

The flow out of the gases is more efficient through the twin exhausts, which themselves have been redesigned with gradual radius bends. The twin mufflers are 78mm shorter, saving weight and improving performance.

The radiator and fork shrouds are narrower and the front mudguard is designed to channel air more efficiently to the radiator. The body panels are covered with tough, scratch-resistant graphics and allow the rider to move easily while riding.

SINGLE MINDED WINNER
An engine, with three riding modes, to help you focus on a top step finish.
Mode 1 is the base map and provides a smooth, linear throttle response, making the engine’s power much more usable in a wide range of conditions. Mode 2 tones down engine performance – useful when you’re feeling tired – while Mode 3 delivers power in a more responsive way, similar to the first mode on the CRF450R.
A new four-valve Unicam head incorporates a new finger rocker design, reducing the engine dimensions and increasing the lift of the inlet valves by 0.5mm to 10mm. The exhaust valve lift is also increased by 0.85mm to 8.8mm.
A better angle
Narrower valve guide angles and two-way valve seat machining smoothens the gas flow to improve downdraft into the inlet ports – it boosts flow from the outlet ports too. Now with a 13.5 compression ratio, the engine develops an 11% increase in peak power; it’ll get you off to a forceful start.
