PISTON KIT 91-94 KTM300 72.00, WOSSNER 8012DA FORGED 54630015044

The Wossner 8012DA piston kit features a 72.00mm bore (actual 71.93mm) and is engineered for exceptional strength and optimal heat transfer to the 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. Made in Germany, this kit includes essential parts for a reliable rebuild and is compatible with KTM 300 models from 1990 to 1994.
