Wossner Pro Series Piston Kit

Experience enhanced engine performance and durability with the Wossner Pro Series Piston Kit. Engineered for 4-stroke motorcycle engines, this kit delivers superior power and reliability, making it an ideal upgrade for enthusiasts and racers.

Description

The Wossner Pro Series Piston Kit is meticulously crafted to elevate your motorcycle's engine performance. Each piston is precision-forged from aerospace-grade aluminum alloy, ensuring exceptional strength and lightweight characteristics. Optimized machining techniques maintain critical strength in areas like the crown and skirt wall cross-section, while reducing overall mass for quicker throttle response. This forged piston kit features a permanent Molybdenum Disulphite (Moly) skirt coating, specifically designed to reduce friction and minimize piston rock. This not only contributes to quieter operation but also aids significantly in the engine's break-in process, extending the lifespan of your motorcycle piston. With a high 13.5:1 compression ratio and a 90.00 mm bore size (89.94 mm piston diameter), this kit is engineered for maximum power output in 4-stroke engines. The comprehensive kit includes the piston, durable nitride-coated steel and cast rings, a high-quality pin, and clips, providing everything needed for a complete and reliable installation. Wossner's commitment to quality ensures a robust and high-performing upgrade for your engine's 400 cc displacement.
