Piston Kit 85-86 RM125 54.50, Wossner 8123D050 Suzuki MX

Description

This Wossner forged piston kit features a 54.50mm bore with a +0.50 oversize specification and is intended for Suzuki RM125 models from 1985 to 1986. Manufactured in Germany, the piston is designed with an elliptical profile to provide a uniform bearing surface under thermal expansion. This reduces localised pressure and the risk of piston collapse while promoting efficient heat transfer from the combustion chamber to the cylinder walls.

Features

  • Forged piston construction for high structural integrity

  • Elliptical design promotes even load distribution during heat expansion

  • Optimised heat transfer from combustion chamber to cylinder walls

  • Made in Germany

  • Includes piston, pin, locks, and ring set
