Wossner Forged Piston Kit - 76.98mm Bore - 250cc - Size C - 8559DC

Elevate your motorcycle's engine performance and reliability with the Wossner Premium Series Piston Kit. Engineered for 250cc 4-stroke engines, this kit delivers a superior upgrade, ensuring quiet operation and enhanced power output for demanding riders.

Description

The Wossner Premium Series Piston Kit is meticulously crafted to meet the rigorous demands of high-performance motorcycle engines. Forged from aerospace-grade aluminum alloy, each piston guarantees exceptional strength and durability, capable of withstanding extreme combustion pressures. The design incorporates optimized machining techniques that achieve an ideal balance of lightness and structural integrity, particularly in critical areas like the crown and skirt wall cross-section. This precise engineering contributes to a responsive engine feel and extended component life.

A key feature of this Wossner 250cc 4-stroke piston kit is its advanced Molybdenum Disulphite (Moly) skirt coating. This permanent, high-quality coating significantly reduces friction between the piston and cylinder wall, minimizing wear and piston rock for quieter operation and improved overall performance. The Moly coating also aids in the crucial engine break-in process, ensuring a smooth start to your engine's new life. With a compression ratio of 12.5:1 and a precise piston diameter of 76.98 mm, this kit is designed to optimize combustion efficiency and power delivery for your 250cc 4-stroke motorcycle.
