PISTON 73-81 MAICO 250 68.50, FORGED WOSSNER 8031D150 KIT

Wossner 68.50mm (68.43mm) forged piston kit is designed for Maico MC 250 and GS 250 models from 1973 to 1981. Engineered for strength and precision, this piston ensures efficient heat transfer to the cylinder walls, providing uniform expansion and reducing localized pressure. The elliptical design distributes thrust loads evenly, preventing piston collapse. Manufactured in Germany, it meets high-quality standards for reliable performance.
