Industry Leading Suspension

The industry-leading, fully adjustable KYB® spring-type fork suspension with speed sensitive damping provides exceptional balance between handling and bump absorption for race-winning performance. In addition to new settings, cylinder diameter is up 1mm to increase rigidity and the mid-speed valve is has changed from coil to leaf spring for improved oil flow and damping.

As well as the smaller tank and slimmer shrouds, the YZ450F benefits from a newly designed seat that is around 20mm lower at its rear section and 8mm lower at the front - as well as being 9mm slimmer. This gives a much flatter seating position, giving you increased front/rear mobility when shifting your weight forwards or backwards

slide 2

The YZ450F is the most complete racing package, and as well as it advanced engine and frame, this MXGP-bred winner runs with trick suspension systems. The class leading AOS forks feature new internals and settings that result in even better damping performance - and the rear shock comes with a lighter spring and increased reservoir capacity
