This Wossner forged high-compression piston kit features a 96mm bore size (95.96mm actual) and is a standard high-compression fitment for Kawasaki KX450F models from 2013 to 2014. Precision-engineered in Germany, the piston includes a dome design that increases compression and improves performance. Its elliptical profile ensures even load distribution under heat expansion, contributing to durability and consistent engine response.
