Description

This Wossner forged piston kit is intended for Yamaha YZ250 (1992–1998) and WR250 (1992–1999) two-stroke models, featuring a 68.01mm bore (+0.01mm oversize). Designed for high performance and longevity, the piston utilises an elliptical shape to enhance load distribution and thermal expansion tolerance, helping to reduce localised pressure points and prevent structural failure. Manufactured in Germany, it ensures efficient combustion heat transfer to cylinder walls for stable engine operation.

Features

Forged piston for high strength and durability
Elliptical profile improves uniform bearing surface under heat
Reduces thrust load concentration and minimises risk of collapse
Facilitates combustion heat transfer for consistent performance
Made in Germany with precision engineering
