Vortex 488AZB-45 CAT5 Black Aluminum 45-Tooth Rear Sprocket

The Vortex 488AZB-45 is a CAT5 series 45-tooth rear sprocket machined from high-strength aluminum and finished in a striking black anodize with contrasting silver CNC-machined highlights. Engineered for motorcycle racing and performance street applications, this sprocket delivers an ideal combination of light weight, durability, and precision fit.

Vortex's CAT5 process anodizes the aluminum billet first, then CNC machines the final profile — resulting in a sprocket body with rich color and bright silver accent cuts that won't fade or peel. The unique Vortex-patented tooth geometry promotes smooth chain engagement and extended sprocket life.
