To figure speed @ given rpm:
(Primary gear ratio)X(6th gear ratio)X(sprocket ratio)= Final ratio
(RPM/Final)X(tire circum.)X(60)/5280= mph @ chosen rpm in chosen gear.
You can plug in different rpm, or gear ratio's to figure out shift points etc...
This does NOT include tire growth, which means the speed will actually be a little greater than calculated.
It's just physics....
