Product Details

The Vortex 780ZR-45 is a lightweight, high-performance aluminum rear sprocket designed as a direct OEM replacement or performance upgrade for sport motorcycles. Engineered from 7075-T6 aerospace-grade aluminum, this sprocket delivers an excellent strength-to-weight ratio while significantly reducing unsprung rotational mass compared to a standard steel sprocket.

Key Features:

  • 45-tooth rear sprocket for optimized acceleration and gear ratio tuning
  • Precision CNC-machined from 7075-T6 aluminum for maximum strength and durability
  • Hard anodized finish resists corrosion and wear for extended service life
  • Precise tooth geometry ensures smooth, consistent chain engagement
  • Lightweight construction reduces unsprung mass for improved handling response
  • Direct bolt-on fitment — no modifications required
  • Compatible with 520 pitch chain (ZR series)

The Vortex VTX series sprocket is a popular choice among street riders and track day enthusiasts looking to fine-tune their motorcycle's performance. Changing to a 45-tooth rear sprocket can improve low-end torque and acceleration response. Vortex is an ISO 9001-certified manufacturer known for precision-machined powersports components.
