PISTON KIT 86-88 YZ125 56.75, WOSSNER 8118D075 YAMAHA MX
This Wossner 56.75mm (+0.75 oversize) forged piston kit is designed for Yamaha YZ125 models from 1986 to 1988. Featuring a forged build and elliptical design, the piston is engineered for thermal expansion control, even thrust load distribution, and reliable performance in two-stroke engines. Manufactured in Germany, it ensures efficient heat transfer from the combustion chamber to the cylinder walls under demanding conditions.
