Wossner Pro Series Piston Kit for 4-Stroke

Elevate your motorcycle's performance with the Wossner Pro Series Piston Kit, engineered specifically for high-performance 4-stroke engines. This complete kit provides superior durability and optimized power delivery, ensuring your ride runs smoother and stronger with a 14.0:1 compression ratio.

Description

Designed for the demanding conditions of 4-stroke motorcycle engines, the Wossner Pro Series Piston Kit delivers unparalleled reliability and power. Crafted from a robust forged aluminum alloy, this piston features a precise 95.95 mm diameter, designed for a standard 96.00 mm bore. Its lightweight construction, combined with a tight piston wall clearance, significantly contributes to a quieter running engine and reduced vibration. Wossner's advanced engineering includes a specialized skirt coating, which actively minimizes friction during operation and enhances crucial break-in performance. Further boosting its longevity and efficiency are the enhanced piston pin oiling slots, radial boss machining, and annular grooves, all meticulously designed to provide superior wrist pin lubrication. The piston also incorporates a ring land treatment, ensuring an improved ring seal and optimal oil control, which are vital for maintaining engine health and consistent performance. With a high 14.0:1 compression ratio and, where applicable, a double-bridged forging design, this Wossner 4-stroke piston kit is built to withstand extreme pressures and deliver maximum power output. This comprehensive kit includes everything needed for a robust rebuild: the piston, rings, wrist pin, and pin locks.
