Description

Designed by Wossner, a leader in high-performance engine components, this 4-stroke piston kit is crafted from robust forged aluminum alloy, ensuring exceptional strength and longevity under extreme conditions. The kit is precision-engineered to deliver an impressive 14.4:1 compression ratio, boosting your engine's power output and responsiveness. Featuring a bore size of 78.01 mm and a piston size of 77.97 mm, it provides optimal clearance for efficient operation.

Advanced lubrication is central to this Wossner piston kit, incorporating enhanced piston pin oiling slots, radial boss machining, and annular grooves. These features work in concert to significantly improve wrist pin lubrication, reducing friction and wear for extended component life. The lightweight piston design, combined with a tight piston wall clearance, contributes to a quieter running engine. Furthermore, the skirt is specially coated to minimize friction and promote a superior break-in performance, while the ring land treatment ensures an improved ring seal and precise oil control. For ultimate resilience, the piston features a double-bridged forging design where applicable, making this an ideal choice for a high-performance motorcycle engine rebuild kit.
