Gearing commander! Nice!

Want to see how a gearing change will effect your performance?
You can enter in your sprocket and tire size and it will show you RPM vs MPH.

I was trying to figure out my RPM's at hwy speeds for my KX500 Supermoto.
Here is stock:

Here is the numbers with my current gearing:

Then, I changed the rear wheel size for the use of a 17" rear wheel:

It should be said that just because you put the numbers in there, does not mean your engine will pull it
Do I think my stock KX500 engine will pull 124 MPH?
NO

With a few mods?
Maybe

Will I have the hair to hold the throttle on for that long to test that theory?
We'll see

Thanks goes to Motorrad for posting this tool over at kxriders.
