Elevate your engine's performance and durability with the Wossner Premium Series Piston Kit. Engineered for 250cc 4-stroke engines, this kit delivers exceptional power and reliability, making it an ideal choice for enthusiasts and professionals seeking a top-tier upgrade.

Description

The Wossner Premium Series Piston Kit for 250cc 4-Stroke engines is meticulously crafted to meet the rigorous demands of high-performance motorcycles. Each piston is precision-forged from aerospace-grade aluminum alloy, ensuring unparalleled strength and a lightweight design. This optimized machining maintains critical strength in areas like the crown and skirt wall cross-section, while reducing overall mass for quicker throttle response. A key feature is the permanent Molybdenum Disulphite (Moly) skirt coating, which significantly reduces friction, minimizes piston rock, and aids in the crucial break-in period, leading to quieter operation and extended engine life. Designed for a 14.0:1 compression ratio, this piston kit is built to enhance power output and efficiency. With a 79.00 mm bore size and a piston diameter of 78.96 mm, it provides a precise fit for your 250cc 4-stroke engine. This comprehensive kit includes everything needed for a complete piston replacement: the piston, high-quality nitride coated steel rings, a durable piston pin, and secure clips.
