Wossner Premium 4-Stroke Forged Piston Kit - 250cc - Size A - 8666DA

Unleash the full potential of your engine with the Wossner Premium Series Piston Kit, engineered specifically for 250cc 4-stroke motorcycles. This high-performance piston kit delivers superior durability and optimized power output, making it an essential upgrade for any serious rider or engine builder.

Description

The Wossner Premium Series Piston Kit is meticulously crafted to elevate your motorcycle's performance. Each piston is precision-forged from aerospace-grade aluminum alloy, ensuring exceptional strength and longevity under extreme operating conditions. Designed with an aggressive 13.4:1 compression ratio and a precise 76.96 mm piston diameter, this Wossner 250cc 4-stroke piston kit is optimized for maximum power and efficiency. The advanced dual-ring design, featuring nitride-coated steel and cast rings, provides superior sealing and reduces blow-by, contributing to consistent power delivery.

A key feature of this high-performance piston is its permanent Molybdenum Disulphite (Moly) skirt coating. This innovative coating significantly reduces friction and piston rock, leading to quieter operation, improved engine response, and an extended lifespan for your engine components. The optimized machining processes ensure lightness without compromising strength in critical areas like the crown and skirt wall cross-section, providing a perfectly balanced and robust component for your motorcycle engine rebuild. Each kit includes the piston, rings, pin, and clips, providing everything needed for a complete and reliable installation.
