Description

The Wossner Premium Series Piston Kit is meticulously crafted from a high-strength forged aluminum alloy, designed to withstand the extreme demands of high-performance 4-stroke engines. With a precise 78.00 mm bore size and a 13.9:1 compression ratio, this piston is engineered to deliver significant power gains and improved throttle response. Its advanced design incorporates enhanced piston pin oiling slots, radial boss machining, and annular grooves, all working together to provide superior wrist pin lubrication. This not only reduces friction and wear but also extends the overall lifespan of critical engine components.

Experience a quieter and smoother running engine thanks to the lightweight piston design and tight piston wall clearance. The piston skirt features a specialized coating, drastically reducing friction during break-in and throughout the engine's operation, contributing to improved performance and efficiency. Furthermore, the ring land treatment ensures an optimal ring seal and precise oil control, vital for maintaining consistent power output and preventing unwanted oil consumption. This Wossner 4-Stroke Piston Kit, including the piston, rings, wrist pin, and pin locks, is a testament to Wossner's commitment to quality and is ready for installation in your motorcycle engine.
