PISTON KIT 2021-22 KX250F 77.97mm, HIGH COMPRESSION WOSSNER 8994DB, Kawasaki
Wossner 8994DB high compression piston kit with a bore of 77.97mm. This piston kit features a 14.5:1 compression ratio and a compression height of 20.18mm with a 52.20 stroke. Wossner forged pistons are superior in strength and design, engineered to provide the best possible path for combustion chamber heat transfer to cylinder walls. They are 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-W8820.B.WO.HC. Includes ring set RIK78.00, clips CW16, and pin WP070-SP.
