The new model’s liquid-cooled, four-stroke, electric start engine features an all-new cylinder head with a larger and improved intake port shape and new exhaust camshaft profile straight from the MXGP dominant YZ250F.
These mods, along with other refinements like revised engine balancer and gear shift cam help to produce stronger mid to top-end power and increased peak power, while retaining class-leading low-end torque.
Tuned specifically for the 2022 WR250F, the updated lightweight aluminium, bilateral beam frame and new engine mounts have been redesigned with all-new flex characteristics to improve bump absorption, traction, and cornering performance.
Settings on the industry-leading, fully adjustable KYB coil spring-type fork with enhanced speed-sensitive damping have been revised to suit the new machine and off-road conditions. And the link-type rear suspension features a KYB shock with revised damping characteristics to match the updated chassis.
Other chassis components such as the top triple clamp, handlebar mounts, and front axle have also been redesigned to complement the new frame – and like the frame these changes are based on the winning YZ250F.
New Dunlop Geomax EN91 ISDE-winning tyres have been specified for improved performance over a wide variety of terrain.
Improved braking performance is achieved with newly engineered lighter front brake caliper with larger surface area brake pads and redesigned front 270mm disc. A new speed sensor ring sends information to an all-new user-friendly multifunction meter that houses both engine and low fuel warning lights.
Riders can adjust their engine performance straight from their smartphone using the onboard wireless connectivity through the free of charge Yamaha Power Tuner app. Once settings are dialled-in, you can choose between two user-defined ECU maps on the fly via the handlebar mounted dual-mode engine map switch.
The new model will continue to provide the edge out on the trails, with the ideal blend of user friendliness and high performance. Features such as electric start, advanced fuel injection and a front-positioned intake with rear-positioned exhaust layout delivers the widest spread of power while maintaining reliable performance and balance for excellent mass-centralisation.
When combined with a lightweight, sharp-handing chassis and industry leading suspension package, the new WR250F continues to offer the fastest way across tight and technical terrain while also providing the widest smile possible.
Complemented by new next-generation Team Yamaha Blue colours and graphics, the 2022 WR250F reflects Yamaha’s race-winning pedigree. The new model is fitted with a full power ECU and comes with ADR compliance so can be fully road registered in all states. A free Off-Road Competition Kit is also offered for owners who wish to set up their WR250F to ride on closed courses.
