Product Details

The Vortex 523ZB-51 is a 51-tooth, 520-pitch steel rear sprocket designed as a direct OEM replacement or performance upgrade for compatible motorcycles. Engineered by Vortex Racing — a trusted name in motorcycle drivetrain components — this sprocket delivers reliable power transfer, precise chain engagement, and long-lasting durability under demanding riding conditions.

Key Features:

  • 51 Teeth — Provides a lower final drive ratio for increased low-end torque and acceleration
  • 520 Chain Pitch — Compatible with standard 520-series drive chains
  • Steel Construction — Offers excellent strength and wear resistance for extended service life
  • Precision Machined — CNC-machined for accurate tooth profile and proper chain mesh
  • Direct-Fit Design — Engineered to match OEM bolt patterns for straightforward installation
  • Vortex ZB Series — Part of Vortex's proven steel sprocket lineup trusted by street and track riders

Whether you're replacing a worn rear sprocket or fine-tuning your gearing for a specific track or riding style, the Vortex 523ZB-51 is a dependable, performance-grade choice built to Vortex's exacting standards.
