WÖSSNER Forged Piston — Manufacturer Ref: 8185D050
Designed for motocross, this Wössner forged piston is manufactured in Germany by specialists in engine components for 2-stroke and 4-stroke engines. Its aluminum construction and treated anti-friction skirt facilitate temperature rises and limit friction during the high RPMs typical of motocross.
Designed as a replacement engine part, this Wössner piston adheres to the oversize dimensions of 0.50 mm and is primarily intended for the displacements and models listed by the manufacturer. It is compatible with YAMAHA YZ 80 (1982 and 1983 models), making it suitable for motocross enthusiasts seeking an alternative original manufacturer engine part, machined and controlled according to German standards.
Before installation, check the bore size of your cylinder and follow the assembly recommendations (piston/ring clearance, circlip installation, and lubrication of the pin). For any restoration or preparation, this piston provides a reliable and traceable base for your motocross engine.
