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!

    Heavy

    I thought this sprocket was supposed to be light. It is easily twice as heavy as the all aluminum sprocket I removed, but it is is 2 teeth smaller. Needless to say, it better last for a long time to make it worth the extra cost and weight.

    Had to put it to the test

    ok so i was looking at the reviews for the chain/ sprocket set and a lot of them said the aluminum sprockets chipped teeth and wore out really quick. So i had to put it to the test, so i took to the road and torqued that sprocket and chain as hard as i could. I beat the absolute snot out of it, i put at least 6 hard road hours on it. The chain barely stretched and the sprocket had next to no wear on it!! When i ordered these they were at my house NEXT day with standard shipping!!! 5/5 would easily buy again! The only thing i have to say is that i probably wouldn't but a aluminum sprocket on a 450 (probably stick with a steel)

    Just Works

    Not a very complicated part, but it is fairly light and the cheapest countershaft sprocket I could find. Works as expected.
