This Wossner forged piston kit is manufactured for Suzuki RM250 models from 1996 to 1997, offering a 68.00mm standard bore. Produced in Germany with premium forged materials, it features an elliptical design that ensures even bearing surface expansion under heat, minimising localised stress and the risk of piston collapse. Its construction enhances combustion heat transfer to the cylinder walls, delivering consistent performance for two-stroke engines.
