Front Sprocket Question

Davey_the_Great · 12-11-2023, 09:03 PM

Looking to go from a 13 tooth to 17 tooth on a 520 chain.
Are there any reliable or preferred vendors to buy from?
New to the forum and new owner so just trying to figure out best options.

That's a pretty big jump. If you haven't already, check to see if there is room in the front sprocket area to fit a 17 tooth. Both at the front but also at the rear, near the swingarm.

More typically you can go up a tooth or two. You might have to do a combination of larger front and smaller rear to get the ratio you want.

More than likely a 14 tooth will be the largest that will fit.

Thanks for replying back, most appreciated. Do you have a suggested vendor or website that is reliable and go to for these types of parts?

You can get the front sprocket on Amazon. https://amzn.to/48eRXWI

I've started adding parts on my website to have all the information in one place. I still have a lot to add to it. https://jerryhawk250.com/index.php/kpx-parts/
