Wossner Pro Series Piston Kit for 250cc 4-Stroke Engines

Elevate your motorcycle's performance with the Wossner Pro Series Piston Kit, engineered for demanding 250cc 4-stroke engines. This premium kit delivers superior power, durability, and reliability for riders seeking optimal engine rebuild components.

Description

The Wossner Pro Series Piston Kit is meticulously crafted to meet the rigorous demands of high-performance 250cc 4-stroke engines. Each forged aluminum piston is designed for exceptional strength and durability, ensuring reliability under extreme conditions. Featuring a precise 78.01 mm bore and a high 14.6:1 compression ratio, this kit is engineered to maximize power output and responsiveness. The piston skirts are treated with a permanent Molybdenum Disulphite (Moly) coating, significantly reducing friction and piston rock. This advanced coating not only contributes to a quieter operation but also aids in the critical break-in process, extending engine life and improving overall performance. Optimized machining techniques ensure lightness without compromising strength in crucial areas like the crown and skirt wall cross-section. This high compression piston kit includes a dual-ring setup, providing excellent sealing and oil control for consistent power delivery. Whether you're rebuilding a race engine or upgrading for enhanced street performance, this Wossner motorcycle engine rebuild kit offers the quality and precision you need.
