2014 Honda CRF450 overview

Delivering improved bottom-end torque, the CRF450R’s 449cm3 single-cylinder engine benefits from new Dual Fuel injection timing and updated twin rear silencers while the clutch features lighter springs ­– with no loss of durability. These modifications are aimed at providing a direct, yet sensitive connection to the rear tyre enhancing rear wheel traction and drive plus the rider’s feel for available grip. Work on the intake and exhaust ports by the CRF450R’s development engineers has also produced improved over-rev and power at peak rpm.

The sixth generation aluminium twin-beam frame remains unchanged for 2014, as do the aluminium swingarm and Pro-Link rear suspension linkage. Rebound and compression damping have been refined on the company KYB rear shock, and the 48mm KYB front forks receive revised internals for improved damping response. The CRF450R’s styling features red and white graphic design which underlines the Honda racing lineage.
