PISTON KIT 91-94 KTM300 72.50, WOSSNER 8012D050 FORGED
The Wossner 8012DA (+0.50) forged piston kit features a 72.50mm bore (actual 72.43mm) and is engineered for superior strength and efficient heat transfer. Its elliptical design ensures a uniform bearing surface under heat expansion, minimizing localized pressure and distributing thrust loads evenly to prevent piston collapse. This kit is made in Germany and includes a lock part number CW18, pin part number WP039, and two ring sets with part number RSB7250. Specifications include a 297 cm³ display volume, 72.00mm stroke, 0.07mm clearance, and 29.70mm compression height. The compression ratio is 2-stroke for both Wossner and OEM.
