Product Details

The Vortex 920AZK-39 is a 39-tooth aluminum rear sprocket designed for motorcycles running a 920 chain pitch. Machined in the USA from aerospace-grade billet aluminum, this sprocket delivers a significant weight reduction over stock steel units, reducing rotating mass for improved throttle response and performance.

Key Features:

  • 7075 T6 billet aluminum construction for maximum strength-to-weight ratio
  • 39-tooth rear sprocket for precise gearing configuration
  • 920 chain pitch compatibility
  • Black anodized (ZK) finish — PTFE hardcoat bonds to the aluminum surface for increased durability and reduced friction
  • 100% CNC-machined in the USA to tight tolerances
  • Lightweight design reduces rotating mass for improved acceleration and deceleration response
  • Race-proven by professional teams in Motocross, Supercross, Road Racing, and Flat Track disciplines

Vortex Racing has been producing top-tier motorcycle drivetrain components for over 15 years. Each sprocket is manufactured and tested to meet the demands of professional racing, making the 920AZK-39 equally suited for competitive track use and spirited street riding.

Everything went smoothly. Thanks.

It was a good product my first one blew up so I needed another

THMOTORSPORTS responded and shipped my purchases of Auxbeam products very quickly. When received, everything looked to be in great shape. They also had the best prices of several vendors that I looked at. I would strongly recommend anyones next purchase to take a good look at THMOTORSPORTS as they definitely delivered on this purchase.

Easy to order and process

Great as long as it gets delivered by Thursday

Excellent quick delivery

It would have been better if you listed the dimensions so hopefully it fits

Everything went smooth, no complaints

great!
