Wossner 92.00mm (91.95mm) forged piston kit is designed for Husaberg FC 400 and FE 400 models from 1996 to 2005. 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.
