Electric Starter System
Utilizing a compact starter motor and ultra-lightweight lithium battery, the YZ450F brings the convenience of push-button starting to the racetrack, for effortless restarts under pressure, and relaxed riding when the clock isn’t ticking.
An updated cylinder head, piston, cam profiles, cylinder geometry and much more work together to give YZ450F riders the best balance of open-class power with controllability.
Yamaha’s bilateral beam frame features new main spars, engine mounts and engine mounting position to further centralize mass and provide an ideal balance between cornering feel and straight-line rigidity.
Yamaha continues to use spring-type forks with refined, speed-sensitive damping to give industry-leading suspension performance straight out of the box. 2018 brings updated settings to match the updated frame and engine layout.
Adjustable Handlebar Mounts
The 4-position adjustable handlebar mounts are rubber mounted to improve comfort and reduce handlebar vibration, while the handlebar itself is lighter to centralize overall mass.
Yamaha’s unique embedded graphics are built into the bodywork for extended durability, resisting both peeling and damage, with all new styling for 2018.
