Vortex 610ZB-45 Blue 45-Tooth 530-Pitch Aluminum Rear Sprocket

The Vortex 610ZB-45 is a 45-tooth, 530-pitch aluminum rear sprocket finished in a striking blue anodized coating with contrasting silver machined highlights. Designed for performance street and track riders who demand lightweight drivetrain components without sacrificing durability.

Key Features:

• 45-Tooth / 530-Pitch — direct-fit rear sprocket engineered for bikes running 530-chain setups
• Lightweight CAT5 aluminum construction — reduces rotating mass for improved throttle response and acceleration
• 100% CNC machined in the USA — manufactured to precise tolerances using a specially formulated alloy per Vortex specifications
• Blue anodized finish — anodized before CNC machining, producing the iconic two-tone look with silver machined highlights on the teeth and sweeps
• Vortex patented saber-tooth groove design — unique tooth profile engineered to increase sprocket longevity and improve chain engagement
• Corrosion-resistant finish — anodized coating protects against oxidation and everyday wear

Vortex aluminum rear sprockets are a trusted choice for racers and performance-oriented street riders. The 610ZB-45 allows riders to fine-tune their final drive ratio for improved low-end acceleration compared to a lower tooth-count sprocket, making it ideal for technical courses or stop-and-go riding environments. As with all aluminum sprockets, regular chain cleaning every 300–400 miles is recommended to maximize service life.
