Wossner Forged Piston Kit - 84.01mm Bore - 300cc - Size B - 8991DB

Elevate your motorcycle's performance and reliability with the premium Wossner 300cc Piston Kit, engineered for demanding 4-stroke engines. This high-quality, forged piston kit is designed to deliver superior durability and reduced friction, ensuring a quieter operation and improved power output for your ride.

Description

The Wossner Standard Series Piston Kit is meticulously crafted to meet the rigorous demands of modern 4-stroke motorcycle engines. Each piston is precision-forged from aerospace-grade aluminum alloy, providing exceptional strength and heat resistance while maintaining an optimal lightweight design. This meticulous construction, combined with an optimized machining process, ensures durability in critical areas such as the crown and skirt wall cross-section without compromising on overall lightness. Featuring a dual ring design and a precise 84.01 mm bore with a 83.96 mm piston diameter, this kit is specifically tailored for 300cc engines with a robust 12.6:1 compression ratio. The piston's skirt is treated with a permanent molybdenum disulphite (Moly) coating, a crucial feature that significantly reduces friction and piston rock. This not only contributes to a quieter engine but also aids in the crucial break-in period, extending the lifespan and enhancing the performance of your engine. When undertaking an engine rebuild, choosing a Wossner forged piston kit means investing in a component that offers both high performance and lasting reliability.
