Monster Energy® Yamaha Racing Edition Inspired by the YZ450F raced by the Yamaha Supercross team, the Monster Energy® Yamaha Racing Edition features an aggressive color and graphics package that stands out from the crowd.
Ultimate Open Class YZ® More Power. Better Handling. Simply put, the 2021 YZ450F™ is better everywhere. With a more compact motor, a thoroughly refined and balanced chassis and improved ergonomics, the YZ450F gives the rider the ability to perform at their best, lap after lap.
Yamaha Power Tuner App Yamaha’s free of charge and industry-leading Power Tuner app puts the flexibility and precision tunability of the GYTR® Power Tuner into your smartphone. Make fueling and ignition timing changes instantly and upload them to the bike for ultimate track-side tuning, or use the handlebar-mounted switch to change fueling maps on the fly.
Compact and Cutting-Edge Fuel-Injected Engine Inside the ultra-compact new motor, a high-compression cylinder head, forged piston, aggressive cam profiles and much more work together to give YZ450F riders the best balance of open-class power with controllability. Plus, the electric start makes it even easier.
Advanced Alloy Frame Yamaha’s bilateral beam aluminum frame features updated main spars, triple clamps and engine mounting points that centralize mass and provide an ideal rigidity balance between cornering feel and straight-line confidence.
Class-Leading Suspension Yamaha's spring-type forks with refined, speed-sensitive damping give industry-leading suspension performance straight out of the box.
Cylinder Head The YZ450F's potent motor includes combustion chamber geometry with steeper valve angles, aggressive cam profiles, a high 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.
Smoother Shifting Gear widths and shapes improve shifting feel and precision without sacrificing Yamaha's legendary reliability under racing conditions.
Bilateral Beam Frame The YZ450F 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 YZ450F takes rider confidence to new levels.
New Braking Systems The rigid front caliper and compact rear caliper work with the pads and discs to boost brake feel and controllability while the 240mm rear brake rotor dissipates heat more efficiently for more consistent performance under racing conditions.
Suspension Tuning The front and rear damping, tuned in concert with the chassis, 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.
Triple Clamp with Adjustable Handlebar Mounts The top triple clamp design balances rigidity for improved steering feel while the 4-position adjustable handlebar clamp is rubber-mounted for comfort, reduced handlebar vibration and easily tunable bar position.
Embedded Graphics Yamaha’s unique embedded graphics are built into the bodywork for extended durability, resisting both peeling and damage.
Race-Winning Details The YZ450F includes top-spec details, including 1-1/8” aluminum tapered handlebars, wider yet lighter foot pegs, a quick-adjust clutch perch, stylish blue rims and gold chain.
