RPM= mph x axle ratio x 336
----------wheel diameter inches
RPM= 62 x (4.11 x .759) x 336
---------------------24
RPM = 2707.7
thats 5th gear overdrive and standard size wheels, you might find that after market wheels are bigger, go measure

well yeah dude, if your total wheel diameter including the tyre = 26"
then your RPM will be very close to 2500.
