Description
When you’re pushing a 2-stroke engine to its limits, the piston is ground zero for performance and reliability. The Wossner 8942DB kit delivers the durability and precision needed to handle sustained high RPM operation without sacrificing responsiveness. This complete kit eliminates the guesswork—everything you need comes together to maximize power delivery and engine longevity.
Built from 4032 T6 forged aluminum and engineered using Finite Element Analysis, this piston withstands extreme heat and load cycles that stock alternatives simply can’t match. The permanent skirt coating reduces friction across the board, translating to faster acceleration and more consistent performance lap after lap. Whether you’re racing YZ250F or YZ250FX models from 2016-2019, this is a bolt-in upgrade that pays dividends immediately.
