Description
The Wossner Piston Kit delivers the durability and precision your YZ450F demands, whether you’re pushing hard at the track or logging hours in the dirt. Factory pistons wear, lose compression, and rob you of throttle response—this complete kit restores your bike’s snap and reliability with German-engineered components that handle sustained high-load abuse. At 12.5:1 compression ratio, you’re getting a proven balance of top-end power and detonation safety for both stock and mildly modified builds.
