It's hard to improve on what is already a proven race winner. But we've made some changes that are going to keep the CRF450R at the head of the pack. The thumping 449cc engine has new intake and exhaust ports to improve bottom end torque, and new Dual Fuel injection timing provides better throttle response. Updated rear silencers help smooth the power delivery and because there's power to burn we've introduced lighter yet more durable clutch springs to help you tame the beast.
The tight turning, hard scrubbing, sixth generation aluminim twin-beam frame is complemented by ergonomics that are absolutely designed for racing, allowing the rider to work with the bike and move intuitively. For 2014 both the front forks and rear shock have been revised to improve dampening response. There is no question the 2014 CRF450R is the ultimate MX weapon.
The 2014 CRF450R is the open class motocross bike champions choose. Sixth generation aluminium twin-beam frame and superior ergonomics, this bike works with you to win.
Delivering improved bottom-end torque, the CRF450R's 449cc single cylinder engine benefits from new Dual Fuel injection timing, revised engine porting, and updated rear silencers. The ultimate power machine, refined to continue winning.
