yamaha YZ450F


Tune in to victory.

The all-new engine comes with a lighter cylinder that maximizes the winning potential of the high compression head, forged piston and aggressive cam profiles. And the YZ450F’s digital Power Tuner lets you make instant trackside engine mapping adjustments and gain a real advantage in all riding conditions.

Its new aluminium bilateral frame comes with thicker down tubes and thinner main spars for reduced weight and sharper handling – while the industry-leading coil spring-type forks and linkage rear suspension deliver exceptional balance.
