PISTON 73-81 MAICO 440 83.00, FORGED WOSSNER KIT 8099D100

Wossner 83.00mm (82.92mm) forged piston kit is designed for Maico MC 440 and MD 440 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. A hard Teflon skirt coating ensures a precise fit and optimal conformability to the cylinder bore. Manufactured in Germany, it meets high-quality standards for reliable performance.
