Wossner 640cc 4-Stroke Piston Kit

Unleash the full potential of your 4-stroke engine with the premium Wossner 640cc 4-Stroke Piston Kit. Engineered for superior performance and exceptional durability, this high-performance piston kit is meticulously crafted to deliver a significant upgrade to your motorcycle's power and reliability.

Description

The Wossner Standard Series Piston Kit is the ultimate choice for riders seeking enhanced engine performance and longevity. Each piston is precision-forged from aerospace-grade aluminum alloy, ensuring unparalleled strength and the ability to withstand the extreme demands of high-revving 4-stroke engines. With an optimal 97.95 mm piston diameter, this kit is designed for a 640 cc displacement engine, providing a precise fit and reliable operation.

A key feature is the advanced Molybdenum Disulphite (Moly) skirt coating, applied permanently to reduce friction and minimize piston rock. This not only contributes to quieter engine operation but also significantly improves overall performance and aids in the critical break-in process. The optimized machining ensures maximum lightness without compromising strength in crucial areas like the crown and skirt wall cross-section. The kit includes everything needed for a complete piston overhaul: the forged aluminum alloy piston, high-quality Nitride Coated, Steel, and Cast piston rings, a durable piston pin, and secure clips, all designed for long-lasting engine reliability.
