Description

The Wossner Pro Series Piston Kit is meticulously crafted to elevate the performance of your 250cc 4-stroke engine. Forged from aerospace-grade aluminum alloy, this piston ensures superior strength and longevity, critical for high-revving applications. Its advanced design features optimized machining that maintains robust strength in key areas like the crown and skirt wall cross-section, while simultaneously reducing overall weight for improved responsiveness. A standout feature is the permanent Molybdenum Disulphite (Moly) skirt coating, specifically engineered to significantly reduce friction, minimize piston rock, and facilitate a smoother break-in period. This results in quieter operation and enhanced power delivery. With a compression ratio of 14.1:1, this dual-ring piston is designed to maximize combustion efficiency, translating into noticeable gains in horsepower and torque. Each kit includes the piston, high-quality nitride coated steel and cast rings, a piston pin, and clips, providing a comprehensive solution for your engine rebuild or upgrade.
