2021 Yamaha YZ450FX
HIGHLIGHTSCRAFTED FOR YOUR NEXT OFF-ROAD ADVENTURE
Featuring a new, more powerful engine, an updated frame, and the smartphone Power Tuner app to dial in the bike's settings to your style and conditions, the 2021 YZ450FX is power – tuned to perfection. Developed from the newest YZ450F motocross model, the 2021 YZ450FX includes added features and unique settings that make it the ultimate woods racer.
POWER TUNER APP
Yamaha's exclusive Power Tuner app puts the flexibility and precision tunability of the GYTR Power Tuner into your smartphone. Make fuelling and ignition timing changes instantly and upload them to the bike via the onboard Wi-Fi system for the ultimate in track-side tuning.
POWERFUL ENGINE
The YZ450FX's already potent engine was treated to a host of go-fast refinements, including new 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.
PERFORMANCE CHASSISThe aluminum frame features all-new flex characteristics that give riders the ultimate combination of precise cornering performance, traction and bump stability. Revised front and rear suspension damping, tuned in concert with the updated chassis, improves 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.
