WR450F Promotions

Model Description

Master of all trades

The all-new WR450F gives you a whole new level of controllability for ultimate performance on all types of fast, slippery and technical terrain. Equipped with Yamaha’s potent next generation 450cc engine and running with a compact new aluminium chassis – both developed directly from the latest MXGP race-winning YZ450F – the all-new WR450F puts you in charge.

Producing higher levels of strong and linear power, the newly developed 450cc reverse-head engine is lighter and faster than ever. The enduro-specific ECU and 5-speed wide ratio transmission deliver increased performance and traction over a wide speed range – and the renewed Power Tuner app makes it easier to select the right mapping for total control in widely varying track and weather conditions.

Equipped with an all-new aluminium chassis, the WR450F feels more compact and agile than ever. Super-slim seamless bodywork and a flatter seat make weight shifting quicker and easier for the highest level of manoeuverability – and the best-in-class KYB suspension is lowered by 10mm and runs revised settings for increased low speed cornering performance.
