Vortex 347ZK-52 CAT5 Aluminum Rear Sprocket 52T Black Anodized

The Vortex 347ZK-52 is a 52-tooth CAT5 aluminum rear sprocket finished in a striking black anodized coating with contrasting silver machined accents. Engineered for performance-focused riders, this sprocket delivers the durability and precision that Vortex Racing is known for across both street and track applications.

• 52-Tooth Count: Higher tooth count provides increased low-end acceleration and improved throttle response at the cost of top-end speed — ideal for technical tracks or aggressive street riding
• CAT5 Aluminum Construction: Machined from a specially formulated lightweight aluminum alloy per Vortex specifications, significantly reducing rotating mass compared to steel
• Black Anodized Finish with Machined Accents: The ZK-series finish features a black hard-coat anodized surface with contrasting silver CNC-machined highlights for a clean, race-inspired appearance
• Patented Tooth Design: Vortex's unique, patented tooth geometry increases sprocket longevity and promotes smooth chain engagement
• 100% CNC Manufactured in the USA: Precision machined to tight tolerances ensuring concentricity, quieter operation, and consistent power delivery
• Bolt Pattern 347: Model-specific carrier pattern — verify fitment for your specific motorcycle make, year, and model before ordering

Replacing worn OEM sprockets with the Vortex 347ZK-52 is a straightforward upgrade that improves drivetrain efficiency and allows riders to fine-tune their gear ratios. For best results and even wear, replace the front sprocket and drive chain at the same time.
