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 exceptional performance and durability, this high-compression piston kit delivers the power and reliability serious riders demand.

Description

The Wossner Pro Series Piston Kit is meticulously crafted for discerning motorcycle enthusiasts seeking a significant upgrade in engine performance. Each Wossner 250cc 4-Stroke Piston Kit features a precision-forged aluminum alloy construction, ensuring superior strength and resilience under extreme conditions. The advanced design, including an optimized machining process, reduces overall weight without compromising critical structural integrity in areas like the crown and skirt wall. This results in a lighter, more responsive engine feel. With a high 14.4:1 compression ratio and a precise 76.00 mm bore size, this kit is designed to boost horsepower and torque. The piston skirts are treated with a permanent Molybdenum Disulphite (Moly) coating, which significantly reduces friction, minimizes piston rock, and aids in the break-in process, leading to quieter operation and extended engine life. The dual-ring design, featuring nitride-coated steel and cast rings, provides excellent sealing and oil control for consistent power delivery.
