ATV Sprockets

Whether you just need to replace a worn out sprocket, or you are looking to re-gear your machine, Rocky Mountain ATV/MC has a wide variety of front and rear ATV sprockets to help you get the job done.

When you are looking to make a change in the acceleration or speed of your machine, changing the teeth on your sprockets can make all the difference. If you are looking for:

  • Better Acceleration – Subtract teeth from the front sprocket, or add teeth to the rear sprocket, as this will gear your bike down.
  • Faster Top Speed – Add teeth to the front sprocket, or subtract teeth from the rear sprocket, as this will gear your bike up.

When you do change the teeth of your sprocket, make sure you run the appropriate size chain. If you:

  • Add one or two teeth to the front or rear sprocket, then add two links to the stock chain length.
  • Subtract one tooth from the front or rear sprocket, then use the stock chain length.
  • Add two or more teeth to the front or rear sprocket, then add two links for every two teeth added.
  • Subtract two or more teeth from the front or rear sprocket, then subtract two links for every two teeth subtracted.

We have a huge variety of high quality sprockets from brands like Renthal, Primary Drive, Pro X, Supersprox, Talon and more. Check them out today!

  • Renthal Front Sprocket

    Renthal Front Sprocket

    Stephen in CA

    On point.

    I went with this Renthal steel front sprocket/counter-shaft sprocket due to reviews and price. Price is fair and qaulity is good so far. About 12 hours on it and no noticeable wear. I take very good care of my chain and sprockets. I expect this to last a long time. Fits my YZ's counter-shaft perfectly.

  • Vortex Rear Steel Sprocket

    Vortex Rear Steel Sprocket

    Stephen in CA

    Perfect fit and lasts.

    Fit perfect on my YZ. Looks amazing, I really like the design, seems lighter than most steel sprockets I have. Price is good. Color is holding up well. I have about 15 hours on it, no wear so far. At least none that the naked eye can see. Will for sure buy again.

  • Pro X Rear Sprocket Bolt Set

    Pro X Rear Sprocket Bolt Set

    Shawn in WA

    broke on install, not recommended

    I put these on a 1990 rmx 250. first, the head of the nut is too large so the bolt didn't reach the locking plastic, so thread lock is needed. I started to torque the nuts down and only got to 15lbs and the head of the bolt broke off. That was the end for me, I ordered oem. cost about $10 more but was a much better product. If this bolt broke while I was riding it could have done a lot of damage! I try to cut costs with my ole bike, but this is not the place to do it.
