PISTON KIT 90-93 YZ125 57.00, WOSSNER 8114D100 YAMAHA MX
The Wossner 8114D100 piston kit features a 57.00mm bore (actual 56.94mm) and is designed for exceptional strength and optimized heat transfer to the cylinder walls. The forged, elliptically designed piston ensures a uniform bearing surface during heat expansion, minimizing localized pressure and evenly distributing thrust loads to prevent piston collapse. Manufactured in Germany, this kit includes essential components for reliable engine performance. Features include forged piston construction for enhanced strength and durability, engineered for efficient combustion chamber heat transfer, elliptical design for a uniform bearing surface under thermal expansion, reduced localized pressure, and prevention of piston collapse. Made in Germany. Specifications include a bore size of 57.00mm (actual 56.94mm), 124cm³ display, 50.70mm stroke, 0.06mm clearance, 2 stroke compression ratio (Wossner and OEM), and 28.00mm compression height. Cross-reference OEM part numbers include Wossner Piston Kit Part No: 8114D100, Lock Part No: CW16, Pin Part No: WP036, Ring Set Part No: RSB5700, and Rod Part No: P2047.
