Renthal Ultralight Rear Sprocket for 428 Chain

Elevate your motorcycle's drivetrain performance with the Renthal Ultralight 428 Rear Sprocket. Engineered for peak efficiency and durability, this premium component significantly reduces unsprung weight, ensuring a noticeable improvement in power delivery and handling.

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. Its innovative tooth profile is a key feature, allowing the chain to roll smoothly on and off the sprocket. This design minimizes friction, reduces drivetrain noise, and extends the lifespan of both the chain and the sprocket, ensuring consistent, efficient power delivery mile after mile. The sleek black finish adds a professional, performance-oriented aesthetic to your bike's drivetrain.
