PISTON KIT 10-22 RMZ250 77mm A, 8781DA WOSSNER SUZUKI 12111-49H00-0F0
Piston kit with 77mm bore and 76.96mm actual bore size. Wossner 8781DA (STD) piston kit. Wossner forged pistons are superior in strength and design, engineered to provide the best possible path for combustion chamber heat transfer to cylinder walls. 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. Part number 56-W951.A.WO. Lock P/N CW16, Pin P/N WP070, Ring Set P/N 770XAS-2. Display (cm3) 249, Hub stroke (mm) 53.60, Clearance (mm) 0.04, Wossner compression Ratio: 13.60:1, OEM Compression ratio: 13.20:1, Dome volume (cm3) +0.10, Compression height (mm) 29.00, Theoretical weight (G) 19.50.
