The Wossner 8022DC piston with a 67.02mm bore (66.96mm actual size) is crafted for high durability and performance, specifically fitting Suzuki RM250 (1989-1995) and RMX250 (1993-1995) models. Produced in Germany, this forged piston is designed to enhance heat transfer efficiency to the cylinder walls. Its elliptical design ensures even load distribution under thermal expansion, preventing localised stress and piston collapse.
