PISTON KIT 85-86 CR125 55.50, WOSSNER 8127D150 HONDA MX

The Wossner 8127D150 piston kit is specifically engineered for Honda CR125 models from 1985 to 1986. It features a forged construction that delivers enhanced strength and optimised heat dissipation from the combustion chamber to the cylinder walls. The elliptical piston design ensures an even bearing surface under thermal expansion, minimising the risk of localised stress and piston failure. Made in Germany, this kit includes all essential components for precise fitment and performance.
