Fair, that is awesome. Thanks for putting them all in one place.

the mph one does nothing for me. I entered it all in and it just sits there. I must be doing something wrong.

works fine for me. Only when using Internet Explorer. 13, 200, 1 should get you 15.something.

This is a great way to see "how fast" someone could relatively go on a motor bike at a certain rpm. I used it with a 26" rim 11tooth drive sprocket, 36tooth rear sprocket, and an rpm of 2200. It gave me the speed of 52mph. But somehow this does not seem right. But I don't know when I buid my bike I will put a tach and a speed gauge to see how close it is.

454 you forgot to add in the gear reduction on the clutch gear, that makes a big difference. I'm not sure what the reduction ratio is though.
