Vortex 630ZR-45 Silver 45-Tooth 630-Pitch Aluminum Rear Sprocket

The Vortex 630ZR-45 is a 45-tooth, 630-pitch aluminum rear sprocket finished in a silver (ZR) anodized color with contrasting machined accents. Engineered for street and performance motorcycle applications, this sprocket is 100% CNC-manufactured in the USA using a specially formulated aluminum alloy developed to Vortex's proprietary specifications.

Key Features:

• 630 Chain Pitch: Designed for use with 630-pitch drive chains — ensure all drivetrain components share the same pitch
• 45 Teeth: Delivers a higher final drive ratio for improved low-end torque and acceleration compared to lower tooth-count options
• Lightweight Aluminum Construction: Reduces rotating mass to improve throttle response and put more power to the pavement
• Vortex Patented Tooth Design: Unique saber-tooth groove geometry increases sprocket longevity and chain engagement
• Silver (ZR) Anodized Finish: Corrosion-resistant anodized finish with contrasting silver machine cuts for a premium appearance
• 100% CNC Manufactured in the USA: Machined to tight tolerances for precise fitment and consistent performance
• Specially Formulated Alloy: Aluminum compound developed per Vortex specifications for optimal strength-to-weight ratio

Vortex rear sprockets are a trusted choice among racers and performance street riders alike. Always replace the front sprocket, rear sprocket, and drive chain as a complete set to prevent accelerated or uneven wear. Confirm chain pitch compatibility before installation.
