Wossner Pro Series Piston Kit for 250cc 4-Stroke

Elevate your motorcycle's performance with the Wossner 250cc 4-Stroke Piston Kit, engineered for durability and efficiency. This high-quality kit provides everything you need for a robust engine rebuild or upgrade, ensuring quiet operation and improved power delivery.

Description

The Wossner Pro Series Piston Kit is meticulously crafted to deliver exceptional performance and longevity for your 250cc 4-stroke engine. Each piston is precision-forged from aerospace-grade aluminum alloy, ensuring unparalleled strength while maintaining optimal lightness through advanced machining processes. This meticulous design strengthens critical areas like the crown and skirt wall cross-section, providing a reliable foundation for high-stress engine environments. A permanent Molybdenum Disulphite (Moly) skirt coating significantly reduces friction and minimizes piston rock, contributing to quieter operation and a smoother break-in period. With a robust 12.8:1 compression ratio, this high-performance piston kit is designed to enhance power output and engine response. The included Nitride Coated, Steel, and Cast rings work in harmony with the piston's 74.96 mm diameter to maintain a superior seal, further boosting efficiency. This comprehensive kit includes the piston, rings, pin, and clips, making it a complete solution for a performance-focused engine overhaul.
