Forged piston designed for 2-stroke and 4-stroke engines, machined and inspected by WOSSNER in Germany. Built to withstand the demands of off-road use, this aluminum alloy piston features a compact structure and a friction-treated skirt to minimize friction during the opening and closing phases of the cylinder. Delivered ready to install with ring, circlips, and pin.
Ideal for cross preparations and original replacements on vintage motorcycles, this piston fits the listed models (notably the MAICO 250 from 1979–1981). Before installation, check the bore, piston/cylinder clearances, and adhere to the manufacturer's installation and break-in recommendations. Manufacturer reference: 8031D150.
