New For 2021
- CYLINDER HEAD: The WR450F's already potent engine was treated to a host of go-fast refinements, including combustion chamber geometry with steeper valve angles, more aggressive cam profiles, a higher compression piston with low friction rings, longer connection rod, larger exhaust head pipe connector, a high flow air filter, more efficient breather system and more—all while fitting under a smaller and lighter magnesium valve cover.
- REVISED BILATERAL BEAM FRAME: The WR450F aluminum frame features flex characteristics that give riders the ultimate combination of precise cornering performance, traction and bump stability. By tuning the rigidity balance of the chassis with changes to the lateral beams and engine cradle tube thickness as well as engine mounts, top triple clamp and front axle, the 2021 WR450F takes rider confidence to new levels.
- UPDATED SUSPENSION TUNING: The 2021 WR450F features revised front and rear damping tuned in concert with the updated chassis to improve cornering performance, traction and bump absorption. With smoother chassis movement, the rider is able to make the most of the engine's exceptional power with greater confidence.
- BRAKING SYSTEMS: More rigid front caliper with pads and disc boost brake feel and controllability. The front brake rotor dissipates heat more efficiently, for more consistent performance under racing conditions.
