*USE THESE GEAR RATIO FORMULAS TO HELP MAKE YOUR DECISION ON THE RATIOS YOU NEED*

To calculate MPH in any gear:                RPM X TIRE HEIGHT              = MPH
                                               GEAR RATIO X RING & PINION X 336

To calculate RPM in any gear:    MPH X GEAR RATIO X RING & PINION X 336   = RPM
                                                                      TIRE HEIGHT 

Note: Remember to do all the individual multiplication functions first before dividing the numerator (top value) by the denominator (bottom value).  Use this formula for each of the forward gears.  This will also allow you to produce a very useful gear chart.
