The Wossner 8111DA (STD) piston kit features a 54.00mm bore (actual 53.94mm) and is engineered for superior strength and efficient heat transfer to cylinder walls. The forged, elliptically designed piston ensures a uniform bearing surface during heat expansion, reducing localised pressure and evenly distributing thrust loads to prevent piston collapse. Manufactured in Germany, this kit provides reliable engine performance and is specifically designed for the 1994 Kawasaki KX125.
