Vortex 523ZB-53 Black Aluminum 520-Pitch 53-Tooth Rear Sprocket

The Vortex 523ZB-53 is a 53-tooth, 520-pitch aluminum rear sprocket finished in a sleek black anodized coating. Engineered for motorcycle riders who demand precision gearing and reduced drivetrain weight, this sprocket is 100% CNC machined in the USA from a specially formulated aluminum alloy to Vortex's exacting specifications.

Key Features:

• Chain Pitch: 520
• Tooth Count: 53 teeth
• Finish: Black anodized aluminum
• Construction: 100% CNC manufactured in the USA
• Material: Specially formulated aluminum alloy per Vortex specifications
• Patented tooth design engineered for increased sprocket longevity and smooth chain engagement
• Lightweight design reduces rotating mass for improved power transfer to the pavement

A larger rear tooth count like 53T raises the overall gear ratio, delivering stronger low-end acceleration and quicker throttle response — ideal for tight circuits or aggressive street riding. Pair with a compatible 520-pitch front sprocket and chain for a complete drivetrain upgrade. As with all Vortex sprockets, ensure all three drivetrain components (front sprocket, rear sprocket, and chain) share the same 520 pitch.
