Wossner Pro Series Piston Kit for 250cc 4-Stroke

Elevate your engine's performance and durability with the Wossner Pro Series 250cc piston kit. Engineered for discerning riders, this high-performance 4-stroke piston kit delivers exceptional power output and reliability for your motorcycle.

Description

Experience the pinnacle of engine reliability and power with the Wossner Pro Series Piston Kit. Meticulously engineered for 4-stroke engines, this kit is specifically designed to optimize performance in 250cc displacements. Each piston is precision-forged from aerospace-grade aluminum alloy, ensuring superior strength and a lightweight profile crucial for high-revving applications. The crown and skirt wall cross-sections are optimized through advanced machining, maintaining robust integrity while minimizing unnecessary mass. With a high 13.5:1 compression ratio and a 77.02 mm bore size, this Wossner piston kit is built to transform your engine's power delivery.

A key feature is the permanent Molybdenum Disulphite (Moly) skirt coating. This advanced coating significantly reduces friction between the piston and cylinder wall, leading to quieter operation, improved longevity, and a more efficient break-in process. The reduced piston rock contributes to consistent performance over time. The complete kit includes the piston, high-quality nitride coated steel rings, a durable piston pin, and secure clips, providing everything needed for a comprehensive engine rebuild or upgrade. Trust Wossner's commitment to quality for a piston kit that delivers on the track and the trail.
