PISTON KIT YZ85 YZ80 49.00, WOSSNER 8188D200 YAMAHA MX
Wossner Piston Kit 8188D200 is a forged performance piston featuring a 49.00mm bore (+2.00 US Bore). This German-manufactured piston offers excellent thermal management and mechanical reliability. Its elliptical profile provides a consistent and uniform bearing surface during thermal expansion, minimising high-stress zones and reducing the risk of piston collapse during intense use. Forged construction delivers high durability and strength under extreme load. The elliptical design reduces localised pressure and distributes thrust evenly. Features enhanced heat dissipation from the combustion chamber to the cylinder walls and precision engineering and manufacturing in Germany. Specifications include a 49.00 mm bore, 48.95 mm actual piston diameter, 47.80 mm stroke, 82 cm³ displacement, 0.05 mm clearance, and 26.00 mm compression height. Compression ratio is 2-stroke for both Wossner and OEM. Cross-reference OEM part numbers include Wossner Piston: 8188D200, Lock: CW14, Pin: WP058, Ring Set: RSB4900, and Rod: P2008.
