YZ450F based engine

The power unit is based on the current YZ450F engine but with specific enduro settings. The reverse fed, mass centralised layout and specifications are the same as the YZ450F engine, but the intake and exhaust systems, fuel injection and ignition advance maps are tuned to provide the fast enduro rider with stronger and longer-lasting pulling power at high rpm.

Smartphone Tuning

On board WiFi means that you can tune the new WR450F to different track conditions using your smartphone. The new Power Tuner app allows you to make fueling and ignition timing changes instantly and upload/share them for the ultimate in track-side tuning. The free Yamaha Power app also allows owners to record race log information and monitor a range of data such as maintenance and system diagnosis, engine run time and more.

Engine Map Switch

A bar-mounted dual engine map switch has been adopted and positioned next to the left lever to enable changes in the engine power delivery characteristics mid-race. This switch allows the rider to select one of two engine maps on the fly at the press of a button to cater for changes in the riding environment.

Industry Leading Suspension

WR450F runs the same KYB air-oil-separate upside-down front fork as the YZ450F but with model-specific enduro settings to provide stable damping force and better transition between the compression and rebound strokes. The rear shock absorber is also based on the YZ450F unit and features enduro model-specific settings. It features a coil with a higher fatigue strength and a weight reduction of approximately 350 grams.

Wide Ratio Transmission

The new WR450F adopts a wide-ratio 5-speed transmission with the same spec and same gear ratios as the 2019 model YZ450FX. This provides both good off-road performance to clear difficult and technical areas as well as high-speed performance for flat dirt sections. Also, the shapes of the dog gears have been revised.
