Product Details

The Vortex 144AZUV4-40 is a 40-tooth aluminum rear sprocket from Vortex's popular VTX series, engineered for performance street and sport motorcycle applications. Precision CNC-machined from high-grade 7075-T6 aluminum alloy, this sprocket delivers an exceptional strength-to-weight ratio over stock steel units, reducing unsprung rotational mass for improved throttle response and acceleration.

Key Features:

  • 40-tooth count for optimized final drive gearing
  • CNC-machined from 7075-T6 aluminum alloy for strength and reduced weight
  • Hard anodized finish for corrosion resistance and extended service life
  • Precision tooth geometry for smooth, quiet chain engagement and reduced chain wear
  • Lightweight design significantly reduces unsprung rotational mass versus OEM steel sprockets
  • Direct bolt-on replacement — no modifications required
  • Available in multiple anodized color options for custom aesthetics
