Hey guys, I really need to know what the 1st through 5th gear ratios are for the 400ex. I can't find them anywhere. I'm trying to input the information into a gearing calculator but I don't know the individual ratios or the primary ratio. Thanks

Thanks guys, but I need the individual ratios if you know them. I can't figure the speed on those graphs because the motor will not be in a quad.
