This website was built to help fellow motorcycle mechanices and weekend warriors enhance their riding enjoyment by teaching how an easy change in sprocket size can change how your bike feels and rides.

It started out as a simple online sprocket sizing calculator, and is growing to include more information to help you tune your motorcycle.

If you have any ideas or comments, please reach out to me.
