Some guys on another site were comparing gear ratios (primary, engine side final and wheel side final). Here is some of it. Makes sense to me ...
Using the specs listed here. It looks like 60 mph should be around 1943 rpm in 6th gear. 5th gear currently 2470?

6th gear .522 Primary 1.795 Engine Side Final .972 Wheel side final 2.615
Wheel Diameter 24.7
RPM= (Final Ratio*MPH*336)/Tire Diameter
(.522*1.795*.972*2.615)=2.381
(2.381* 60*336)/24.7 = 1943.35 ish
