The Wossner 8055DA piston kit features a 54.00mm bore (actual 53.95mm) and is engineered for superior strength and efficient heat transfer to cylinder walls. The forged, elliptically designed piston ensures a uniform bearing surface under heat expansion, minimising localised pressure and distributing thrust loads evenly to prevent piston collapse. Manufactured in Germany, this kit is designed for reliable performance. Features include forged piston construction for maximum strength and durability, optimal combustion chamber heat transfer, and an elliptical design providing a uniform bearing surface during heat expansion. It reduces localised pressure and prevents piston collapse. Specifications include a bore size of 54.00mm (actual 53.95mm), 123 cm³ displacement, 54.00mm stroke, 0.05mm clearance, and 29.50mm compression height. This kit includes a Wossner Piston Kit Part No: 8055DA, Lock Part No: CW15, Pin Part No: WP032, and Ring Set Part No: RSB5400. OEM Part Numbers cross-referenced are 12110-27C06-0F0, 09104763, and 641M05400.
