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

Elevate your motorcycle's engine performance with the Wossner Pro Series 250cc 4-stroke piston kit. Engineered for superior durability and power, this kit delivers exceptional reliability and responsiveness for demanding riders.

Description

Experience a significant upgrade in your engine's heart with the Wossner Pro Series piston kit. This premium Wossner 250cc 4-stroke piston kit is meticulously forged from aerospace-grade aluminum alloy, ensuring exceptional strength and heat resistance under extreme conditions. Its optimized machining not only reduces overall weight for improved throttle response but also maintains critical strength in key areas like the crown and skirt wall cross-section, guaranteeing long-term reliability. The piston features a permanent Molybdenum Disulphite (Moly) skirt coating, specifically designed to minimize friction and prevent piston rock. This results in quieter operation, reduced wear, and a smoother break-in process for your engine. With a high compression ratio of 14.4:1, this kit is engineered to unlock maximum power and efficiency from your 250cc 4-stroke engine. The dual-ring design, featuring nitride-coated steel and cast rings, provides excellent sealing and durability. Each kit includes a precision-engineered piston (with a 75.98 mm diameter for a 76.02 mm bore), high-quality rings, a sturdy pin, and secure clips, providing everything needed for a comprehensive engine rebuild or upgrade.
