Product Details

The Vortex 255AZB-45 is a CAT5 series 45-tooth, 520-pitch rear sprocket machined from aerospace-grade 7075 T6 aluminum and finished in a satin black anodized coating. Designed as a direct performance upgrade over stock steel sprockets, this sprocket reduces rotating mass for sharper throttle response and improved acceleration.

Key Features:

  • Material: 7075 T6 aerospace-grade aluminum — lightweight yet exceptionally strong
  • Finish: Black anodized coating for corrosion resistance and a clean appearance
  • Pitch: 520 — compatible with 520-pitch chains
  • Tooth Count: 45 teeth
  • Construction: 100% CNC machined in the USA to tight tolerances
  • Design: CAT5 series with unique tooth profile for extended sprocket and chain life
  • Specially formulated alloy per Vortex Racing specifications

Vortex Racing sprockets are trusted by professional race teams worldwide. The reduced rotating mass compared to OEM steel sprockets translates directly to improved acceleration and more responsive handling. The black anodized finish resists corrosion and retains its appearance over time.
