About this product
About this product
The Renthal Twinring™ Rear Sprocket offers the ultimate combination of durability and lightweight performance for your motorcycle. Engineered for demanding riders, this sprocket provides exceptional longevity and reduces rotating mass for improved handling and acceleration. Upgrade to Renthal and experience the difference.
Description
Renthal's Twinring™ Rear Sprocket is designed with a unique two-piece construction. The inner ring is machined from Renthal's high-strength Ultralight™ 7075-T6 aluminum, the same material used in their standard sprockets, ensuring minimal weight and maximum power transfer. The outer ring is constructed from durable, electro-less nickel-coated steel, providing exceptional wear resistance and extending the sprocket's lifespan. The outer ring is expanded at 200°C and fitted over the inner, creating an interference fit that, combined with a wave pattern, forms a permanent bond. Flat socket head screws add further strength, especially during side impacts, while also preventing contact with the chain guide. Self-cleaning mud grooves between each tooth prevent dirt buildup, reducing chainwheel wear and minimizing weight. Expect up to three times the lifespan of a standard all-aluminum sprocket, with a weight significantly less than an all-steel equivalent. This 520 chain sprocket with 51 teeth provides optimal power transfer.
