Wossner Pro Series High-Compression 400cc Piston Kit

Unleash superior performance and durability in your 400cc engine with the Wossner Pro Series high-compression piston kit. Engineered from aerospace-grade forged aluminum, this kit delivers exceptional power and longevity for demanding riders, making it an ideal choice for a motorcycle engine rebuild kit.

Description

Elevate your engine's performance with the Wossner Pro Series Piston Kit, meticulously crafted for 4-stroke 400cc engines. This high-compression piston kit features an impressive 11.2:1 compression ratio, designed to boost power output and throttle response. Each piston is precision-forged from aerospace-grade aluminum alloy, ensuring unparalleled strength and durability under extreme operating conditions. The advanced manufacturing process includes optimized machining for lightness, strategically maintaining robust strength in critical areas such as the crown and skirt wall cross-section. This balance of weight reduction and structural integrity contributes to a more efficient and reliable engine. Furthermore, all piston skirts are treated with a permanent molybdenum disulphide (Moly) coating. This advanced coating significantly reduces friction and piston rock, leading to quieter operation, improved performance, and assisting in the critical break-in period. The kit comes complete with a high-quality piston, durable rings (cast, steel, nitride coated), a robust pin, and secure clips, providing everything needed for a comprehensive and successful installation.
