Features


Compact Five-Speed Transmission

Compact Five-Speed Transmission

Tri-shaft transmission layout vertically stacks the transmission shafts, raising the centre shaft and forming a triangle between the crank, drive shaft and main shaft for a lighter, more compact transmission.

High Performance Braking System

High Performance Braking System

A large 270mm front brake rotor is coupled with a Nissin caliper to provide excellent braking  performance. Out back, rear brake feel is improved by reducing the rigidity of the brake hose providing a wider range of control at the pedal.

Strong, Lightweight Wheels

Strong, Lightweight Wheels

Careful computer-aided design of each wheel’s cross-sectional profile shaves weight without sacrificing durability. The YZ450F's rear wheel comes laced with a three-cross-spoke pattern for improved impact absorption and rider feel.

Optimised Air Intake
