This Wossner piston kit is designed for Husaberg FE 650 models from 2004 to 2008 and features a 100.00 mm bore with an actual piston diameter of 99.95 mm. Forged in Germany, the piston provides high strength and thermal efficiency, optimising the heat transfer from the combustion chamber to the cylinder walls. Its elliptical design ensures uniform bearing surface during thermal expansion, distributing thrust loads evenly to reduce localised stress and prevent piston collapse.

Features

• Forged piston construction for enhanced strength
