Description

Unleash the full potential of your 250cc 4-stroke engine with the precision-engineered Wossner Pro Series Piston Kit. Each piston is meticulously forged from aerospace-grade aluminum alloy, guaranteeing exceptional strength and reliability under extreme conditions. The advanced design incorporates optimized machining to achieve an ideal balance of lightness and structural integrity, particularly in critical areas like the crown and skirt wall cross-section. A permanent Molybdenum Disulphite (Moly) skirt coating significantly reduces friction and piston rock, leading to quieter operation, improved longevity, and a smoother break-in process. With a high 14.0:1 compression ratio, this dual-ring piston kit is designed to deliver a noticeable boost in power and responsiveness. The standard Piston Size B, with a 76.77 mm piston diameter and a 76.81 mm bore size, ensures a precise fit for compatible models, making it an ideal choice for serious riders and mechanics seeking a high-performance piston replacement or engine rebuild solution.
