Product Details

The Vortex 523ZK-39 is a 39-tooth, 525-pitch rear sprocket crafted from lightweight aluminum and finished in a durable black anodized coating. Designed for street and track riders who demand precise power delivery and reduced rotational mass, this sprocket is 100% CNC-machined in the USA to tight tolerances.

Key Features:

  • 525 Pitch — Compatible with 525-pitch drive chains
  • 39 Teeth — Bolt-on replacement or gearing upgrade option
  • Black Anodized Aluminum — Lightweight construction reduces rotating mass and resists corrosion
  • 100% CNC Manufactured in the USA — Machined to precise tolerances for concentricity and smooth chain engagement
  • Vortex Patented Tooth Design — Unique tooth geometry extends sprocket service life
  • Specially Formulated Alloy — Built to Vortex's proprietary material specifications for optimal strength-to-weight ratio

The Vortex 523ZK-39 rear sprocket is a direct-fit upgrade over worn OEM sprockets or a tool for fine-tuning your motorcycle's gear ratio for improved acceleration response. Verify fitment using Vortex's year/make/model selector before ordering.
