Product Details

The Vortex 840AZKV4-40 is a 40-tooth aluminum rear sprocket designed for motorcycle road racing and performance street applications. Built in the USA from a specially formulated aluminum alloy to Vortex's exact specifications, this sprocket delivers a significant weight reduction over steel units, reducing rotating mass for improved throttle response and drivetrain efficiency.

Key Features:

  • 40-Tooth, 530 Chain Pitch rear sprocket
  • 100% CNC machined in the USA to tight tolerances
  • Black anodized with machined accent contrast cut finish for a premium appearance
  • Vortex patented tooth design engineered for increased sprocket longevity
  • Specially formulated aluminum alloy per Vortex specifications
  • Lightening cuts reduce overall rotating mass for improved acceleration and deceleration response
  • Unique saber tooth groove geometry minimizes chain wear

Vortex Racing has been manufacturing top-quality motorcycle racing components since 1995, supplying professional race teams across Supercross, Motocross, Road Racing, and Flat Track disciplines. The 840AZKV4-40 is a direct bolt-on upgrade that combines race-proven engineering with an aggressive aesthetic.

Informative and helpful ordered tires and the process was smooth. Shipping company was quite slow compared to others that we've ordered from buy tires just showed up and seemed to be good. Thank you.

Thank you

The only thing that didn't go very well was the time it took to receive the 2nd part of my order. I paid extra for 2 day shipping. It took closer to 6 days to receive my CDI switch box.

Great as long as it gets delivered by Thursday

Quick easy and got my tires fast

Fast and easy

I tried calling several times with no answer. Then an email took a whole day for a response
