I have added a downloads section and placed a neat little spreadsheet in there that will give you the theoretical speed capability of your ride. It has all the KX500 specific information in it right now but there is nothing that will stop you from changing those values to reflect your 250, 650, or what ever bike you have.
Remember, the spreadsheet doesn't take into consideration speed lost to areodynamics etc... Based on the numbers, a bone stock 2001 KX500 is capable of 97mph
