Vortex 491AZR-54 520 CAT5 Aluminum Rear Sprocket 54-Tooth Red

The Vortex 491AZR-54 is a 520-pitch, 54-tooth CAT5 aluminum rear sprocket finished in red anodize with contrasting silver machined highlights. Designed for performance street and track riders, this sprocket delivers a significant weight reduction over OEM steel units, helping reduce rotating mass for improved acceleration and handling response.

Key Features:

• CAT5 Construction: Anodized in red first, then CNC machined from 7075 aerospace-grade aluminum — producing a striking two-tone finish with silver highlights
• Lightweight Design: Aluminum construction is substantially lighter than OEM steel sprockets, reducing rotating mass for better acceleration
• 520 Pitch: Compatible with 520-pitch chain systems (including OEM and conversion setups)
• 54 Teeth: Higher tooth count for increased bottom-end torque and improved acceleration off corners
• Unique Tooth Profile: Vortex's patented tooth design promotes smooth chain engagement and extended sprocket longevity
• 100% CNC Manufactured in the USA: Precision machined to tight tolerances for concentricity and quiet operation
• Specially Formulated Alloy: Material spec developed per Vortex Racing's own standards for optimal strength-to-weight ratio

The Vortex 491AZR-54 is part of the trusted CAT5 sprocket line — the same series relied upon by racing champions. Pair with a matching 520-pitch front sprocket and chain for a complete drivetrain upgrade.
