Wossner Pro Series Piston Kit for 250cc 4-Stroke Engines

Unleash the full potential of your 250cc 4-stroke engine with the Wossner Pro Series Piston Kit. Engineered for peak performance and exceptional durability, this kit provides a significant upgrade for serious riders and rebuilders.

Description

The Wossner Pro Series Piston Kit is meticulously crafted to elevate the performance and longevity of your motorcycle's 250cc 4-stroke engine. Each piston is precision-forged from aerospace-grade aluminum alloy, ensuring unparalleled strength and resistance to the extreme pressures of high-performance riding. Featuring an optimized machining process, these pistons achieve remarkable lightness without compromising structural integrity, particularly in critical areas like the crown and skirt wall cross-section. A key highlight is the permanent Molybdenum Disulphide skirt coating, which significantly reduces friction and piston rock. This advanced coating not only contributes to a quieter engine operation but also enhances overall performance and assists in the crucial break-in period. With a 14.5:1 compression ratio and a precise 78.02 mm bore size (77.98 mm piston diameter), this dual-ring piston kit is designed for optimal power delivery. The complete package includes the piston, high-quality nitride coated steel and cast rings, a wrist pin, and circlips, making it a comprehensive solution for your engine overhaul or upgrade.
