Elevate your engine's performance and reliability with the Wossner Pro Series Piston Kit for 4-Stroke 500cc engines. Engineered from aerospace-grade forged aluminum, this premium piston kit delivers exceptional durability and power. Its advanced design, including a permanent Moly skirt coating, significantly reduces friction and piston rock for a quieter, more efficient ride.

Description

The Wossner Pro Series Piston Kit is meticulously crafted to meet the rigorous demands of high-performance 4-stroke engines, specifically designed for 500cc displacement. Each piston is precision-machined for optimal lightness without compromising strength in critical areas like the crown and skirt wall. Forged from high-quality aerospace-grade aluminum alloy, it ensures superior resilience and a longer lifespan under extreme conditions. The innovative permanent Molybdenum Disulphite (Moly) skirt coating is a key feature, actively working to minimize friction and piston rock, which not only contributes to quieter operation but also enhances overall engine efficiency and assists during the break-in period. With a precise 77.02 mm bore size and an aggressive 13.7:1 compression ratio, this dual ring piston kit is engineered to deliver enhanced power output and responsive throttle feel. The kit includes everything needed for a complete piston replacement: the piston, high-quality Nitride Coated steel cast rings, a robust pin, and secure clips, making installation straightforward for mechanics and enthusiasts alike.
