Wossner Standard Series Piston Kit for 650cc 4-Stroke

The Wossner 650cc 4-Stroke Piston Kit delivers superior performance and durability for your motorcycle engine. Engineered for enthusiasts and professionals, this kit ensures a reliable and powerful upgrade for your ride.

Description

This Wossner Standard Series Piston Kit is meticulously engineered for 650cc 4-stroke engines, offering a significant upgrade in both performance and longevity. Each piston is precision-forged from aerospace-grade aluminum alloy, ensuring exceptional strength and lightweight characteristics. The optimized machining process maintains critical strength in areas like the crown and skirt wall cross-section while reducing overall mass for quicker engine response. A key feature is the permanent Molybdenum Disulphite (Moly) skirt coating, which actively reduces friction and piston rock. This not only contributes to quieter engine operation but also significantly extends piston life and aids in proper break-in. Designed for a precise 10.0:1 compression ratio and a 99.95 mm piston diameter, this kit provides consistent, high-level performance. It includes everything needed for a complete piston replacement: the piston, high-quality nitride coated steel and cast rings, a wrist pin, and clips, making installation straightforward for a robust engine rebuild.
