Description

The Wossner 250cc 4-stroke Piston Kit is meticulously crafted to redefine your engine's capabilities. Each piston is forged from aerospace-grade aluminum alloy, ensuring exceptional strength and an optimized weight for rapid throttle response and sustained durability. Designed with a robust 14.1:1 compression ratio, this kit maximizes combustion efficiency, translating directly into enhanced power output. The piston's skirt features a permanent Molybdenum Disulphite (Moly) coating, significantly reducing friction, minimizing piston rock, and aiding in a smoother break-in process for quiet, improved performance. This dual ring piston design provides excellent sealing, while precision machining maintains critical strength in areas like the crown and skirt wall cross-section. Ideal for a complete motorcycle engine rebuild, this Wossner kit includes the standard size B piston with a 77.96 mm diameter, durable nitride-coated steel and cast rings, the piston pin, and clips, offering a comprehensive solution for restoring or upgrading your engine.
