Now here's a nifty app:


Now you can determine and adjust your gearing with a little info!!!

Here's a better calculator!!! This one is specifically for the 350X!!!


I have to correct myself from another post regarding sprocket size and how it effects speed. The correction is, the smaller your rear sprocket is the faster your speed will be. If you increase the front sprocket the same thing will happen.

Taller tires will also increase your overall speed.

Nice App!!!

Good save... I saw the other post :)

I think the rule is 1 tooth in the front is equal to 3 teeth in the rear when changing gearing.

Thx. Tire size threw me off. I thought the rear sprocket follows the same rules as the rear tires. But they are opposite.

What about the speed chart by Wonderboy?
The graph is a great tool also.

Thx for pointing that out Scuba. I didn't know WB posted an Excel chart. I only remember seeing the pictures!! That works just as well!!! I might have to post a new thread under the MPL and make these charts available as a sticky.
