awesome sight

Is primary drive ratio the number of times the front sprocket turns per once for the rear? And is the final ratio trans gear selected times primary drive ratio? But this does not include the tire size in the equation?

Here is a gearing chart for the 08 that I modified from LDH's gearing chart on www.rogueracing.org. This chart has the gear ratios for the 08 and allows you to take into account different tire sizes if you know the diameter of the tire.

Just download and unzip. You will need to have Microsoft Excel to use it.

The primary ratio is the crank pinion to clutch gear.
