This Wossner forged piston kit with a 90mm bore is a standard replacement designed for all Speedway applications, specifically GM Speedway 499cc engines. Made in Germany, the piston is built for strength and efficient heat dissipation. Its elliptical profile ensures even load distribution under heat expansion, minimising stress and helping to prevent piston failure.
