Product Details

The Vortex 839AZRV4-42 is a high-performance 42-tooth aluminum rear sprocket from Vortex's VTX series, engineered for sport and performance motorcycle applications. Vortex sprockets are CNC-machined from high-grade 7075-T6 aluminum alloy, delivering an exceptional strength-to-weight ratio that reduces unsprung rotational mass compared to steel alternatives.

Key Features:

  • 42-tooth count for optimized drive ratio and acceleration tuning
  • 7075-T6 aircraft-grade aluminum construction for lightweight durability
  • Hard anodized finish for corrosion resistance and extended service life
  • CNC-machined to tight tolerances for precise chain engagement and reduced wear
  • VTX series design with lightening pockets to minimize rotating mass
  • Direct OEM-style fitment — no modifications required

Vortex is a leading manufacturer of performance drivetrain components trusted by racers and enthusiasts worldwide. The 839AZRV4-42 sprocket is a popular upgrade for riders looking to fine-tune gearing for track or street performance while saving weight over a stock steel sprocket.
