WÖSSNER Forged Piston – Manufacturer Ref. 8047D150
Designed and machined in Germany by Wössner, this forged piston is aimed at CROSS riders looking for a robust engine part ready to withstand the demands of high RPMs. Made from forged aluminum, it features a friction-treated skirt to minimize wear in the bore and promote good temperature stability.
The design and finish of the skirt contribute to smoother RPM increases and controlled wear when the engine is under load. This replacement part is suitable for cross applications and corresponds to the machining and bore references indicated on the datasheet.
Notable compatibilities: MAICO 400 (1980, 1981, 1982 – 400 cm3). Before installation, check the piston/cylinder clearance and the manufacturer's recommendations for bore and break-in.
