Wossner Pro Series Dual Ring Piston Kit for 4-Stroke Engines

Elevate your engine's performance and reliability with the Wossner Pro Series Piston Kit, meticulously engineered for demanding 4-stroke applications. This premium kit delivers enhanced power and durability, ensuring your motorcycle operates at its peak for every ride.

Description

Experience superior engine response and longevity with the Wossner Pro Series Piston Kit, a crucial upgrade for any 4-stroke motorcycle. Each piston is precision-forged from aerospace-grade aluminum alloy, offering exceptional strength and reduced weight for optimal performance. The advanced manufacturing process includes optimized machining that maintains robust strength in critical areas like the crown and skirt wall cross-section, while simultaneously achieving an incredibly lightweight design. This kit features a standard size A piston with a 76.96 mm piston diameter and a 77.00 mm bore size, perfectly suited for 250 cc displacement engines. With an impressive 14.1:1 compression ratio, you can expect a significant boost in power and efficiency.

Wossner pistons are equipped with a high-quality, permanent molybdenum disulphite (Moly) skirt coating. This advanced coating drastically reduces friction and piston rock, leading to quieter operation, improved performance, and extended engine life. It also plays a vital role in assisting the break-in process, ensuring a smooth start for your newly built engine. Designed as a dual ring piston, this kit includes everything you need for a complete installation: the piston itself, high-performance nitride-coated steel and cast rings, a piston pin, and corresponding clips, providing a comprehensive solution for your engine rebuild or upgrade.
