PISTON KIT 91-01 RM80 48.45, WOSSNER 8270D100 SUZUKI MX

Wossner forged piston kit with a 48.50mm bore size (48.45mm actual), specifically designed for Suzuki RM80 models from 1991 to 2001 with a US bore. Manufactured in Germany, this piston kit features an elliptical design that supports uniform bearing surfaces under thermal expansion, promotes efficient heat transfer from the combustion chamber, and distributes thrust loads evenly to reduce the risk of piston collapse.

Features

• Forged piston construction for high strength and reliability
