Description

Elevate your engine's reliability and output with the Wossner Standard Series Piston Kit. Meticulously forged from aerospace-grade aluminum alloy, this piston is designed to withstand the extreme demands of high-performance motorcycle engines. With a precise 79.94 mm piston diameter for an 80.00 mm bore (+1.00 mm oversize), it’s specifically tailored for 350cc 4-stroke applications, delivering a robust 9.5:1 compression ratio. The advanced Molybdenum Disulphite skirt coating significantly reduces friction and piston rock, contributing to quieter operation, improved efficiency, and enhanced longevity. Each piston undergoes optimized machining to achieve an ideal balance of lightness and structural integrity, particularly in critical areas like the crown and skirt wall cross-section. This comprehensive kit includes the piston, high-quality nitride-coated steel rings, a durable piston pin, and retaining clips, making it a complete solution for rebuilding or upgrading your engine.
