Vortex 527-57 Silver 57-Tooth 530-Pitch Aluminum Rear Sprocket

The Vortex 527-57 is a 57-tooth, 530-pitch aluminum rear sprocket finished in a silver anodized coating. Designed for road riding and performance use, this sprocket is 100% CNC machined in the USA from a specially formulated aluminum alloy per Vortex specifications and silver anodized to resist corrosion.

Vortex's patented tooth profile is engineered to extend sprocket life and improve chain engagement, making it a popular upgrade over stock sprockets for street and track riders alike. The lightweight aluminum construction reduces rotating mass compared to steel sprockets, helping improve throttle response and overall drivetrain efficiency.

Key Features:

• 57 teeth — higher tooth count for increased low-end torque and acceleration
• 530 chain pitch — matches OEM and aftermarket 530-series drive chains
• 7075-T6 billet aluminum — high-strength alloy for exceptional durability at reduced weight
• 100% CNC machined — precise tolerances for smooth, consistent chain engagement
• Vortex patented tooth design — unique profile increases sprocket longevity
• Silver anodized finish — corrosion-resistant coating with clean, classic appearance
• 527 bolt pattern — fits applications using the 527-series sprocket carrier
