PISTON KIT 92-98 HSV 250 67.50, HUSQVARNA WOSSNER 8015D050

This Wossner forged piston kit is specifically designed for Husqvarna CR250 and WR250 models from 1992 to 1998 and features a +0.50mm oversize with a 67.50mm bore. Precision-engineered and manufactured in Germany, the piston is built for durability in two-stroke applications. Its elliptical shape ensures balanced thermal expansion and stress distribution, minimising the risk of piston collapse and enhancing overall performance through improved heat transfer from the combustion chamber to the cylinder wall.
