This gear calculator is set as default to the 2002 Trophy 1200

When first run, it shows the mph for every 1000 rpm in each gear.

If you wish to set it for any other bike,
Select:

• number of "fixed" transmission ratios
• number of gears

To reset everything back to the defaults, use the "Default to 2002 Trophy 1200" link.

By default, the table on the right will show the mph for each 1000 rpm in all the gears. The increment and the highest rpm may be changed by editing the "rpm increment" and "maximum rpm" values and pressing the "submit" button

There is some error checking on inputs. If it thinks an entry is incorrect, it will highlight the area in red and ask for it to be corrected.
