PISTON KIT 09-12 CRF450R 96 HC, WOSSNER 8768DB HONDA FORGED
Wossner 8768DB forged piston kit for Honda CRF450R 2009-2012. Features a 96.01mm bore and 95.97mm actual bore size with a +0.01mm tolerance. This high compression piston kit includes 2 rings. Wossner forged pistons are superior in strength and design, engineered for optimal heat transfer to cylinder walls. The elliptical design provides a uniform bearing surface under piston heat expansion, eliminating localized pressure and distributing thrust loads evenly to prevent piston collapse. Made in Germany. Specifications include a display volume of 449 cm³, 62.10mm hub stroke, 0.04mm clearance, 13.40:1 compression ratio (compared to OEM 12.00:1), -0.030 cm³ dome volume, and 20.70mm compression height. Part numbers: Lock P/N CW19, Pin P/N WP028, Ring Set P/N 960ADS-2, Rod P/N P4027. Theoretical weight 376 grams.
