Wossner piston kit with a standard bore size of 66.40mm. This forged high-performance piston features a skirt coating and is engineered for efficient heat transfer from the combustion chamber to the cylinder walls. Its elliptical design maintains a uniform bearing surface during thermal expansion, distributing thrust loads evenly and reducing localised stress to prevent piston collapse under high operating stress. Manufactured in Germany, this kit includes a piston, rings (RIK77.00D), pin (WP070), and circlips (CW16). Cross-reference OEM part numbers include Wossner 8305DA and 56-W9989.A.WO.
