WOSSNER 72mm FORGED PISTON KIT B, KTM 300 2T 1991-1994

The Wossner 8012DA (+0.01) piston kit features a 72.01mm bore (actual 71.94mm) and is engineered for superior strength and effective heat transfer to cylinder walls. The forged, elliptically designed piston ensures a more uniform bearing surface during heat expansion, minimising localised pressure and evenly distributing thrust loads to prevent piston collapse. Manufactured in Germany, this kit includes the necessary components for a durable rebuild and is suitable for KTM 300 models from 1990 to 1994.
