Description
The stock piston in your YZ250F won't cut it if you're pushing hard on the track or trail. Wossner pistons are engineered for high-load durability and reduced friction, giving you reliable power delivery lap after lap. This complete kit gives you everything needed for a straightforward top-end refresh without the guesswork.
Built from 4032 T6 forged aluminum, the piston withstands the thermal and mechanical demands of aggressive riding. The permanent skirt coating minimizes friction losses, while T6 heat treatment ensures the material maintains integrity under sustained high-temperature operation. Wossner's FEA-optimized design means every curve and thickness is calculated for performance, not compromise.
Installation is straightforward—the kit includes the piston, rings, wrist pin, and clips, so you have everything required for a complete top-end assembly.
