Description
The stock piston in your KX250F won’t survive sustained high-RPM performance or aggressive riding. Wossner’s 13.5:1 compression ratio piston delivers the reliability and efficiency you need to push harder without sacrificing engine longevity. This is a complete bolt-on replacement that combines German engineering with precision manufacturing—everything included, no additional purchases required.
Built from 4032 T6 forged aluminum and treated with a permanent skirt coating, this piston minimizes friction while reducing piston rock for smoother, quieter operation under load. The T6 heat treatment ensures exceptional thermal stability, critical for 2-stroke engines that operate at punishing temperatures. Wossner designed this kit using Finite Element Analysis to optimize every dimension, balancing strength with lightweight performance.
