Upgrade your motorcycle's performance with the Renthal Ultralight Rear Sprocket. Designed for maximum power transfer and reduced weight, this sprocket will enhance your bike's acceleration and handling. Experience the difference a high-quality sprocket makes.
Description
The Renthal Ultralight Rear Sprocket is CNC-machined, not stamped, and features a computer-aided, ultra-light design to significantly reduce unsprung weight. This reduction in weight translates directly to increased power transfer, giving you improved acceleration and responsiveness. Constructed from high-strength, specially enhanced 7075-T6 aluminum, this rear sprocket is 33% lighter than steel, further reducing weight without compromising strength. The special tooth profile ensures the chain rolls smoothly on and off the sprocket, resulting in extended wear life, reduced noise, and enhanced power delivery. Compatible with 520 chains, this sprocket is an ideal upgrade for riders seeking optimal performance and durability.
