Product Details

The Vortex 920ZB-39 is a lightweight, high-performance aluminum rear sprocket designed as a direct OEM replacement or performance upgrade for motorcycles using a 920 chain pitch. Engineered by Vortex Racing, a trusted name in powersports drivetrain components, this sprocket delivers the precision, durability, and weight savings demanded by both street and track riders.

Key Features:

  • 39-Tooth rear sprocket configuration for optimized power delivery and acceleration
  • 920 chain pitch compatibility — designed to pair seamlessly with 920-series drive chains
  • Constructed from high-strength 7075 aluminum alloy for an excellent strength-to-weight ratio
  • Hard anodized finish provides superior corrosion resistance and extended service life
  • CNC-machined to tight tolerances for smooth, precise chain engagement
  • Lightweight design reduces unsprung and rotating mass for improved handling response
  • Direct bolt-on fitment for compatible motorcycle applications

Vortex sprockets are manufactured to meet or exceed OEM specifications, making the 920ZB-39 a reliable choice for riders looking to maintain or improve drivetrain performance. Whether used for everyday street riding or aggressive track use, this rear sprocket offers the quality and precision Vortex is known for.

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.

Great price with excellent service. I would highly recommend your company!

Fast shipping

Quick delivery and great customer service

My "new" tires are over 8 months old per the manufacturing date code. Since trailer tires are supposed to be replaced every 6 years based on date code, it would be nice if they were less than 6 months old when purchased. Thank you.
