Unleash peak performance in your 250cc 4-Stroke engine with the Wossner Pro Series Piston Kit. This premium Wossner 250cc 4-Stroke piston kit is meticulously engineered to deliver superior power, enhanced durability, and quiet operation for the most demanding riding conditions.

Description

Designed for motorcycle enthusiasts and professionals, the Wossner Pro Series piston kit is a testament to precision engineering. Each forged aluminum piston is crafted from aerospace-grade alloy, ensuring exceptional strength and resilience under extreme pressures. With a high 14.2:1 compression ratio and a precise 78.01 mm bore, this kit is optimized to maximize your engine's power output and throttle response. The advanced manufacturing process includes optimized machining for lightness, maintaining crucial strength in key areas like the crown and skirt wall cross-section, contributing to quicker acceleration and reduced reciprocating mass.

A standout feature is the permanent Molybdenum Disulphite skirt coating. This specialized moly skirt coated piston technology significantly reduces friction and piston rock, leading to quieter operation, improved longevity, and a smoother break-in period. The kit also includes high-quality dual ring piston design with nitride-coated steel and cast rings, providing excellent sealing and oil control. When you choose a Wossner piston kit, you're investing in a complete solution for your engine rebuild, offering unmatched reliability and performance for your 250cc 4-stroke motorcycle.
