PISTON KIT YFM400FW 00-06, FORGED WOSSNER 8901DA 5GH-11631-00-00
This Wossner piston kit features a standard 92.00mm bore with a measured diameter of 84.42mm. The forged piston construction offers superior strength and reliability. Its advanced heat transfer design optimizes thermal efficiency and oil distribution from the combustion chamber to the cylinder walls. The elliptical profile promotes a uniform bearing surface under thermal expansion, and even thrust load distribution reduces localized stress and prevents piston collapse. Manufactured in Germany. Specifications include a 92.00mm bore, 84.42mm diameter, 400 cm³ displacement, 70.50 mm stroke, 0.08 mm clearance, 8.50:1 compression ratio (Wossner) / 10.50:1 (OEM), -2.90 cm³ dome volume, 26.90 mm compression height, CW20 clips, WP052 pin, and 845XSY ring set. Cross-reference OEM part numbers include 5GH-11631-00-00 and 40076M08450.
