PISTON KIT 10-22 RMZ250 77mm C, 8781DC WOSSNER SUZUKI
Wossner 8781DC Piston Kit with a 77.02mm bore and 76.98mm clearance. This Wossner forged piston is superior in strength and design, engineered to provide the best possible path for combustion chamber heat transfer to cylinder walls. It is elliptically designed to provide a more uniform bearing surface under piston heat expansion, eliminating localized pressure and distributing thrust loads more evenly, thereby preventing piston collapse. Made in Germany. This kit includes Lock P/N CW16, Pin P/N WP070, and Ring Set P/N 770XAS-S. Display (cm3) 249. Hub stroke (mm) 53.80. Clearance (mm) 0.04. Wossner compression Ratio: 14.20:1. OEM Compression ratio: 13.20:1. Dome volume (cm3) +0.10. Compression height (mm) 29.00. Theoretical weight (G) 19.50.
