$70.70The Story
This Wossner forged piston kit is engineered for Husqvarna CR250 and WR250 models from 1992 to 1998, featuring a 67.00mm standard bore. Manufactured in Germany, it combines high-strength forging with an elliptical profile that allows uniform expansion under thermal stress. This helps prevent localised pressure build-up and piston collapse. Designed for efficient heat dissipation from the combustion chamber to the cylinder wall, it supports consistent performance in two-stroke engines.
