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 99.96 mm. Forged in Germany, the piston is built for durability and thermal efficiency, supporting optimal heat transfer from the combustion chamber to the cylinder walls. The elliptical design promotes a consistent bearing surface during thermal expansion, reducing localised stress and preventing piston collapse.
