With a higher‑performing engine, an updated lightweight frame, and more, the YZ250F is engineered to race ‑ and win ‑ like a champion.
The YZ250F's already potent motor was treated to a host of refinements, including an all-new cylinder head with an improved intake port shape, new exhaust camshaft profile, a new silencer, and an updated ECU and more—to produce stronger mid- to top-end power and increased peak power, while retaining its class-leading low-end torque.
New air box lid intake ducts have been added for increased air flow with a new high flow air filter, air cleaner boot featuring a new shape for increased flow and a larger diameter throttle body joint.
The YZ250F aluminum frame features all-new flex characteristics that give riders the ultimate combination of precise cornering performance and handling 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 YZ250F takes rider confidence to new levels.
The 2021 YZ250F features revised damping front and rear 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.
A new, more rigid front caliper and compact rear caliper work with new pads and discs to boost brake feel and controllability while the new 240mm rear brake rotor dissipates heat more efficiently, for a more consistent racing performance.
The crank case, cam chain and tensioner, waterpump, clutch basket, and the third, fourth and fifth transmission gears have all been refined to enhance overall durability.
