Wossner Pro Series Piston Kit for 250cc 4-Stroke

Unleash the full potential of your 250cc 4-stroke engine with the Wossner Pro Series Piston Kit. Engineered for superior performance and durability, this kit provides everything you need to rebuild or upgrade your motor with confidence.

Description

This premium Wossner 250cc 4-stroke piston kit is meticulously crafted from aerospace-grade forged aluminum alloy, ensuring exceptional strength and lightweight performance. Designed with a high 14.2:1 compression ratio, it's built to deliver a significant boost in power and throttle response for your motorcycle. Each piston features a permanent Molybdenum Disulphite (Moly) skirt coating, which significantly reduces friction, minimizes piston rock, and aids in the break-in process, leading to quieter operation and extended engine life. The optimized machining processes maintain crucial strength in high-stress areas like the crown and skirt wall cross-section, while also achieving optimal lightness. This Dual Ring piston kit includes durable Nitride Coated, Steel, and Cast rings, along with the piston pin and clips, providing a comprehensive solution for your engine rebuild. With a precise 77.00 mm bore size and 76.96 mm piston diameter, this standard size A piston ensures a perfect fit and reliable operation.
