WÖSSNER Forged Piston – Manufacturer Part No. 8180DA

Designed and machined in Germany by Wössner, this forged piston is aimed at demanding off-road riders who seek a high-quality engine part. Machined from a robust aluminum alloy and featuring an anti-friction treatment on the skirt, it is built to withstand repeated cycles and the stresses of motocross without making unverified technical claims.

  • Oversize Letter: A

The Wössner piston features the necessary dimensions for engines equipped with an oversize A and fits into setups where bore precision is critical. Its treated skirt minimizes friction against the cylinder, and the supplied assembly makes replacement in the workshop easier. This replacement part is particularly suitable for YAMAHA YZ 250 models (1980 to 1982), and it is essential to verify engine compatibility before installation.
