Wossner Pro Series High-Performance Piston Kit

Elevate your motorcycle's engine performance with the Wossner Pro Series 250cc piston kit, engineered for riders demanding superior power and durability. This high-performance 4-stroke piston kit is designed to withstand extreme conditions while optimizing power delivery and engine longevity.

Description

The Wossner Pro Series high-compression piston kit is meticulously forged from aerospace-grade aluminum alloy, ensuring exceptional strength and reduced reciprocating mass. Each forged motorcycle piston undergoes optimized machining, strategically removing material for lightness without compromising critical areas like the crown and skirt wall cross-section. This results in a piston that delivers improved throttle response and higher RPM capabilities. Featuring a robust 14.0:1 compression ratio, this piston kit significantly boosts power output for your 250cc engine. The 76.80 mm bore size standard-size A piston is equipped with a permanent Molybdenum Disulphite (Moly) skirt coating. This advanced coating drastically reduces friction and piston rock, leading to quieter operation, enhanced performance, and assisting in the critical break-in period. The dual-ring design, utilizing high-quality Nitride Coated, Steel, and Cast rings, ensures excellent sealing and oil control, making this an ideal performance engine piston upgrade for serious riders.
