§ 02 / About this part
What it is
The WOSSNER PSTN KT YAM YZ450F STD A, top end. Stocked by Iron Offroad, the UK MX hard parts specialist.
This forged top-end kit is a direct replacement for the original piston in your YZ450F. It sits at the centre of the engine's power production and wears over time. Standard A sizing is designed for cylinders that are still within factory dimensions. Regular replacement is the best way to avoid catastrophic engine failure and maintain peak torque. The kit includes the piston, rings, gudgeon pin, and circlips. Verify the ring end gap and ensure the circlips are fully seated. Lubricate the small-end assembly during the build to prevent wear during the first start. Clean the bore before installation.
