Vortex 452AZB-45 CAT5 Blue 45-Tooth 520-Pitch Aluminum Rear Sprocket

The Vortex 452AZB-45 is a CAT5 aluminum rear sprocket engineered for sport and performance motorcycle applications. Designed for 520-pitch chains and featuring 45 teeth, this sprocket is a direct bolt-on upgrade over heavy OEM steel units, reducing rotating mass for improved acceleration and throttle response.

Manufactured entirely in the USA, each sprocket is 100% CNC-machined from specially formulated 7075-T6 aluminum per Vortex's exacting specifications. The sprocket is anodized first, then CNC-machined, producing a striking blue anodized finish with contrasting silver highlights on the swept areas, mud grooves, and teeth.
