Product Details

The Vortex 604ZK-31 is a 31-tooth steel rear sprocket designed as a direct-fit, high-performance replacement for select motorcycles running a 520-pitch chain. Built to exacting tolerances, this sprocket delivers reliable power transfer and long service life for both street and track applications.

Key Features:

  • Material: Carbon steel alloy manufactured to Vortex specifications for superior strength and wear resistance
  • Finish: Electro-plated satin black finish to prevent corrosion and resist the elements
  • Tooth Count: 31 teeth
  • Chain Pitch: 520
  • Tooth Design: Vortex patented unique tooth geometry increases sprocket longevity and reduces chain wear
  • Construction: 100% CNC machined in the USA for precise concentricity and consistent fitment
  • Bolt Pattern: ZK carrier pattern — verify fitment for your specific application

Vortex Racing sprockets are trusted by professional racers and street riders alike. The steel construction of the 604ZK-31 makes it an ideal choice for high-mileage or demanding riding conditions where durability is the priority. For best results, replace the front sprocket and chain at the same time to ensure even wear across all drivetrain components.

All good very simple

Saia is a horrible freight company. I used to deal with them at my previous job as a shipper. Box had a little damage, paint is rubbed off in a couple areas and swivel wheel assembly was bent. I was able to get it straight. Hopefully it will roll ok once it has weight on it. Not something I would expect for a $1500 item. I had to call Saia several times because I was getting a runaround on the delivery, they kept telling me they would schedule a delivery time. Never did, it showed up at my house unexpected, luckily my wife was still home. Seems like a good product though

It was quick and easy

EASY AND FAST

Easy purchase, the item was shipped and received quickly!

good price

Good experience

Only thing was I thought I was getting a black one and a white one was sent. The picture was black when I bought it on line and didn't see any pic black or white options

Next day delivery was great! No complaints!
