WÖSSNER forged piston, manufacturer reference 8116DA, designed for 2-stroke engines in the motocross segment. Engineered and machined in Germany, this aluminum piston benefits from a forged construction for a dense and homogeneous structure. The skirt receives an anti-friction treatment to reduce hot friction and facilitate the break-in process.
This piston is aimed at motocross riders looking for a replacement part that meets original standards for oversize A cylinders. Its geometry and the skirt treatment are designed to minimize seizure phenomena and stabilize friction between the piston and cylinder during sustained use.
Indicative compatibility: suitable for YAMAHA YZ 125 (1994‑1996) and other machines requiring a piston Ø 53.94 mm in oversize A. Always check engine specifications and bore before installation.
