Description

Experience superior engine performance with the Wossner Pro Series Piston Kit, meticulously crafted for 250cc 4-stroke engines. This advanced motorcycle piston kit features pistons forged from aerospace-grade aluminum alloy, guaranteeing exceptional strength and a lightweight design. Wossner's optimized machining process maintains critical material integrity in key areas like the crown and skirt wall cross-section, providing a perfect balance of lightness and structural robustness. Each piston is treated with a permanent Molybdenum Disulphite (Moly) skirt coating. This advanced coating significantly reduces friction and minimizes piston rock, leading to a quieter operation, improved power delivery, and an extended engine lifespan. The kit's dual-ring design, coupled with nitride-coated steel and cast rings, ensures optimal sealing and wear resistance. With a high compression ratio of 14.4:1, this high-performance piston is designed to maximize your engine's power output and efficiency, making it an ideal choice for a complete engine rebuild kit or performance upgrade.
