Motorcycling Gearing Calculator

gearing calculator
(of earlier version)
This is a great little number which allows you to enter a variety of different values - gearbox ratios, tyre sizes, sprocket sizes etc -  in order to calculate the machine's speed in any gear at any given rpm. Use is simplicity itself - just plug in the figures for your bike into the pink column on the left side of the sheet. It's set up with standard figures for a Ducati 916, and is in Zipped MS Excel 95 format.
