Vortex 775BZR-53 Black Anodized Rear Sprocket Pitch Sprockets - 53-Tooth 520

The Vortex 775BZR-53 is a 53-tooth, 520-pitch aluminum rear sprocket finished in a striking black anodize with contrasting machined silver accents. CNC-machined in the USA from a specially formulated aluminum alloy, this sprocket delivers the lightweight performance and precision fit that Vortex Racing is known for in both street and track applications.

Key Features:

• 53-Tooth / 520 Pitch — bolt-on fitment for compatible 520-chain drive motorcycles
• Black Anodized with Machined Accents — durable finish with contrasting silver highlights for an aggressive look
• Lightweight Aluminum Construction — reduces rotating mass for improved throttle response and power transfer
• 100% CNC Manufactured in the USA — precision machined to extremely tight tolerances
• Vortex Patented Tooth Profile — unique tooth geometry engineered to extend sprocket longevity
• Lightening Holes — strategically placed cutouts further reduce unsprung rotational weight
• Specially Formulated Alloy — material spec developed by Vortex to balance strength and weight

Upgrading to a higher tooth-count rear sprocket like the 53T increases your gear ratio, delivering stronger low-end acceleration and quicker throttle response — ideal for tight tracks or aggressive street riding. Pair with a matching 520-pitch front sprocket and chain for a complete drivetrain upgrade.
