Description

Experience unparalleled engine performance with the Wossner Pro Series Piston Kit, specifically designed for 250cc 4-stroke engines. This premium piston is meticulously forged from aerospace-grade aluminum alloy, providing superior strength and resilience under extreme operating temperatures and pressures. Wossner's commitment to quality is evident in the optimized machining process, which ensures a lightweight design without compromising crucial strength in areas like the crown and skirt wall cross-section. The piston features a permanent Molybdenum Disulphite (Moly) skirt coating, significantly reducing friction and minimizing piston rock for quieter operation and improved performance. This coating also aids in a smoother break-in period, extending the lifespan of your engine components. With an aggressive 14.6:1 compression ratio, this dual-ring piston kit is engineered to maximize power output and responsiveness. Each kit includes a high-performance piston, durable nitride-coated steel and cast rings, a robust piston pin, and secure clips, providing everything needed for a complete and reliable engine rebuild or upgrade.
