Description

The Renthal Ultralight 428 Rear Sprocket is meticulously engineered to provide superior performance and durability for your motorcycle. Unlike stamped alternatives, this premium rear sprocket is CNC-machined from high-strength, specially enhanced 7075-T6 aluminum, making it an astounding 33% lighter than comparable steel sprockets. This significant reduction in unsprung weight directly translates to improved power transfer, sharper acceleration, and more responsive handling, giving riders a competitive edge.

Designed with a computer-aided ultralight profile, the Renthal 49-tooth 428 Rear Sprocket optimizes strength-to-weight ratio without compromising integrity.
