The Wossner 8022D050 piston with a 67.50mm bore (67.44mm actual size) is designed for high performance and strength, compatible with Suzuki RM250 (1989-1995) and RMX250 (1993-1995) models. This German-forged piston is optimised to enhance heat transfer to the cylinder walls. Its elliptical structure helps maintain uniform bearing surfaces during thermal expansion, preventing localised pressure points and potential piston collapse.
