Description

Experience superior engine reliability and power with the Wossner Pro Series 250cc 4-Stroke Piston Kit. This meticulously crafted piston is forged from high-grade aerospace aluminum alloy, ensuring both remarkable strength and a lightweight profile. Optimized machining techniques maintain structural integrity in critical areas like the crown and skirt wall cross-section, contributing to the piston's overall resilience and performance under extreme conditions. The piston features a permanent Molybdenum Disulphite (Moly) skirt coating, specifically designed to significantly reduce friction and piston rock, leading to quieter operation and improved engine efficiency. This advanced coating also plays a crucial role in assisting with the vital break-in period, extending the lifespan of your engine components. With a high 13.0:1 compression ratio, this high compression piston is engineered to deliver a substantial boost in power and torque for your 250cc 4-stroke engine. Designed for a precise fit, it boasts a 76.00 mm bore size and a 75.96 mm piston diameter (Standard Size A). The kit includes a robust dual-ring setup with high-quality nitride-coated, steel, and cast rings, along with the wrist pin and clips, providing a complete solution for your engine rebuild or motorcycle piston replacement.
