Product Details

The Vortex 920AZK-48 is a high-performance aluminum rear sprocket from Vortex Racing's popular VTX series. Designed as a direct OEM replacement or performance upgrade, this sprocket is precision-machined from lightweight aluminum alloy to reduce unsprung rotational mass and improve throttle response.

Key Features:

  • 48-Tooth configuration for optimized acceleration and gear ratio tuning
  • 520 chain pitch compatible with standard and converted 520 drive systems
  • CNC-machined 7075 aluminum construction for maximum strength-to-weight ratio
  • Hard anodized finish for corrosion resistance and extended wear life
  • Precise tooth geometry for smooth chain engagement and reduced drivetrain noise
  • Direct bolt-on fitment — no modifications required for compatible applications

The Vortex VTX series is a trusted choice among sport bike enthusiasts and racers looking to fine-tune their drive ratio. Swapping to a larger rear sprocket like the 48T delivers snappier acceleration out of corners, making it ideal for tight tracks or aggressive street riding.

The turbo (s475sx-e) has been my best purchase this year. The order was placed at the end of the workday and Thmotorsports shipped it the very next morning, also the box arrived in magnificent condition, the turbo was picture perfect without a blemish. Thmotorsports was the most affordable out of all ten sites that were considered, with top notch shipping. I have to say Thmotorsports was the best choice for my genuine part.

Fast shipping great product!
