WOSSNER 69mm PISTON KIT SUZUKI RM250 1989-1995, RMX250 1989-1999

The Wossner 8022D100 piston with a 69mm bore (68.94mm actual size) is engineered for high durability and strength, fitting Suzuki RM250 (1989-1995) and RMX250 (1993-1995) models. Forged in Germany, it is designed to maximise heat transfer from the combustion chamber to the cylinder walls. The elliptical piston shape promotes even distribution of thrust loads under heat expansion, reducing localised stresses and preventing piston collapse.
