Vortex 454-66 Silver 66-Tooth 525-Pitch Aluminum Rear Sprocket

The Vortex 454-66 is a 66-tooth, 525-pitch silver anodized aluminum rear sprocket built for serious motorcycle performance. 100% CNC manufactured in the USA, this sprocket is machined from a specially formulated alloy to Vortex's exacting standards, delivering a lightweight alternative to heavy OEM steel sprockets that directly reduces rotating mass and improves throttle response.

Vortex's patented saber tooth groove design sets this sprocket apart from the competition, extending service life and optimizing chain engagement for smoother, more consistent power delivery. The silver anodized finish provides corrosion resistance and a clean, race-ready appearance.

Key Features:
