Upgrade your motorcycle's performance and reliability with the high-quality Wossner Pro Series 4-stroke piston kit. Engineered for demanding riders, this kit delivers exceptional power output and durability, making it an ideal choice for engine rebuilds or performance enhancements.

Description

The Wossner Pro Series 4-stroke piston kit is meticulously engineered from a robust forged aluminum alloy to withstand the extreme pressures of high-performance engines. Designed with a precise 88.01 mm bore size and an aggressive 12.5:1 compression ratio, this piston maximizes power delivery and engine efficiency. Key features include enhanced piston pin oiling slots, radial boss machining, and annular grooves, all working in concert to significantly improve wrist pin lubrication and extend component life.

Wossner's commitment to performance is evident in the lightweight piston design, which, combined with a tight piston wall clearance, ensures a quieter running engine and reduced vibration. The piston skirt is specially coated to minimize friction and promote a smoother break-in period, while the advanced ring land treatment optimizes ring seal for superior oil control and sustained power. For applications requiring maximum strength, a double bridged forging design is incorporated where noted, ensuring unparalleled resilience. This comprehensive motorcycle piston kit includes everything you need for a complete installation: the piston, high-quality rings, a durable wrist pin, and secure pin locks.
