Vortex 491ZR-52 Red Aluminum 52-Tooth Rear Sprocket

The Vortex 491ZR-52 is a 52-tooth aluminum rear sprocket finished in a striking red anodized color. Engineered for performance street and track riders, this sprocket is 100% CNC machined from 7075-T6 billet aluminum, delivering an exceptional strength-to-weight ratio that reduces rotating mass and helps put more power to the ground.

Vortex's proprietary saber tooth groove geometry and patent-pending tooth profile set this sprocket apart, promoting even chain wear and extending the service life of both the sprocket and chain. The hard anodized finish bonds to the aluminum surface, providing corrosion resistance and reducing friction for a longer-lasting drivetrain component.
