About this product
Maximize your motorcycle's performance with the Renthal Ultralight Rear Sprocket. This sprocket is engineered for superior power transfer and reduced weight, giving you the edge you need on the track or trail. Experience improved acceleration and handling thanks to its lightweight design.
Description
The Renthal Ultralight Rear Sprocket is CNC-machined, ensuring precision and eliminating the weaknesses of stamped sprockets. Its computer-aided, ultra-light design significantly reduces unsprung weight, leading to increased power transfer and improved handling. Crafted 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 longer wear, reduced noise, and enhanced power delivery. Upgrade to Renthal and feel the difference.
