PISTON KIT 12-18 CRF150R 66.00, 8861DB WOSSNER
Wossner forged piston kit 8861DB is a +0.01mm oversized piston with a 66.01mm bore (measured at 65.96mm). It features a Teflon-coated skirt and precision-engineered forged construction for excellent durability, thermal performance, and a precise fit for high-revving four-stroke engines. Forged construction provides maximum strength and longevity. The elliptical design ensures even pressure distribution during thermal expansion, and it offers high-efficiency heat transfer from the combustion chamber to cylinder walls. The hard Teflon skirt coating enhances fit and bore conformity, reducing localised stress to prevent piston collapse. Made in Germany. Specifications include a bore of 66.01mm (measured 65.96mm), display volume of 149 cm³, stroke of 43.80mm, clearance of 0.05mm, compression height of 20.60mm, Wossner compression ratio of OEM, OEM compression ratio of 11.70:1, dome volume of -1.40 cm³. Part No. 56-W914.B.WO (Wossner 8861DB). Includes ring set 660XKS, lock P/N CW14, and pin P/N WP058.
