Wossner Pro Series Piston Kit for 78.01mm Bore

Unleash the full potential of your 250cc 4-stroke engine with the high-performance Wossner Pro Series 78.01mm piston kit. Engineered for superior durability and power, this kit delivers a significant upgrade for serious riders.

Description

The Wossner Pro Series Piston Kit is meticulously crafted to elevate your motorcycle's engine performance and reliability. Each forged motorcycle piston is precision-machined from aerospace-grade aluminum alloy, ensuring exceptional strength while maintaining optimal lightness. This advanced manufacturing process, combined with an optimized crown and skirt wall cross-section, guarantees robust performance under extreme conditions, making it an ideal 250cc engine upgrade.

Designed for reduced friction and extended lifespan, the piston features a permanent Molybdenum Disulphite (Moly) skirt coating. This specialized coating minimizes piston rock and friction, contributing to quieter operation and a smoother break-in period. With an aggressive 14.5:1 high compression ratio and a dual-ring design, this kit is built to maximize power output. The nitride-coated steel and cast rings ensure excellent sealing and wear resistance, maintaining peak performance over time. The Wossner Pro Series piston kit, with its 77.97mm piston diameter designed for a 78.01mm bore, provides a precise fit for optimal engine dynamics.
