Wossner Pro Series Piston Kit for 250cc 4-Stroke 13.5:1

Elevate your engine's performance and durability with the Wossner Pro Series Piston Kit for 250cc 4-Stroke engines. Engineered for the demands of high-performance motorcycles, this forged piston kit delivers exceptional strength and reduced friction, ensuring a quieter and more efficient power delivery.

Description

The Wossner Pro Series Piston Kit is meticulously designed to optimize the heart of your 250cc 4-stroke engine. Forged from aerospace-grade aluminum alloy, this piston ensures superior resilience against the extreme pressures and temperatures of high-performance riding. Its impressive 13.5:1 compression ratio is engineered to unlock maximum power and responsiveness from your engine, providing a noticeable boost in acceleration and overall output.

Each piston features an advanced Molybdenum Disulphite (Moly) skirt coating. This permanent, high-quality coating significantly reduces friction between the piston and cylinder wall, minimizing wear and tear while promoting a quieter operation and aiding in a smoother break-in process. Optimized machining techniques contribute to a lighter piston without compromising strength in critical areas like the crown and skirt wall cross-section, ensuring both durability and agile engine response. This comprehensive motorcycle piston replacement kit includes everything you need for installation: the piston itself, high-quality nitride coated steel and cast rings, a piston pin, and retaining clips, making it a complete solution for your engine rebuild or upgrade.
