Description

Experience superior performance with the Renthal Ultralight Rear Sprocket, a meticulously crafted component designed to optimize your motorcycle's drivetrain. Unlike conventional stamped sprockets, this CNC-machined sprocket is precisely manufactured from high-strength, specially enhanced 7075-T6 aluminum. This advanced material makes the Renthal Ultralight Rear Sprocket an impressive 33% lighter than comparable steel sprockets, dramatically reducing unsprung weight. The reduction in unsprung mass translates directly into improved suspension response, better handling, and a noticeable increase in power transfer to the rear wheel. Engineered for a 428 chain sprocket setup, this lightweight rear sprocket, with its 47-tooth configuration, features a unique tooth profile that ensures the chain rolls smoothly on and off. This not only extends chain and sprocket life but also minimizes operational noise and maximizes power delivery, making it an essential performance motorcycle part for serious riders seeking an edge.
