Wossner Premium Series Piston Kit for 250cc 4-Stroke

Upgrade your engine's performance and reliability with the Wossner Premium Series Piston Kit, specifically engineered for 250cc 4-stroke motorcycles. This high-quality, forged aluminum piston kit delivers exceptional durability and power, ensuring your ride performs at its peak.

Description

Experience superior engine performance with the Wossner Premium Series Piston Kit, a meticulously crafted component designed for demanding 250cc 4-stroke applications. Each piston is forged from aerospace-grade aluminum alloy, guaranteeing maximum strength and resilience under extreme operating conditions. The advanced manufacturing process includes optimized machining, which reduces overall weight without compromising critical structural integrity in key areas like the crown and skirt wall cross-section. This precision engineering contributes to a more responsive engine and enhanced power delivery.

A standout feature of this high-performance piston kit is the permanent Molybdenum Disulphite (Moly) skirt coating. This advanced coating significantly reduces friction and minimizes piston rock, leading to quieter operation, improved longevity, and a smoother break-in period for your engine. Designed for a 79.00 mm bore with a standard 78.96 mm piston diameter, this kit ensures optimal sealing and an impressive 13.9:1 compression ratio, vital for maximizing horsepower in your 250cc 4-stroke engine. The complete kit includes the piston, high-quality Nitride Coated, Steel, and Cast rings, a wrist pin, and circlips, providing everything needed for a comprehensive engine rebuild.
