What kind of gearing does your bike have? Is your speedo reading Kilometers??? Mine is stock geared a Twin Cam 6 speed and here are the speeds in gears.....
5500 RPM on a stock geared Dyna Fat Bob. Speed verified by GPS multiple runs.

1st gear @ 5500 RPM = 44 mph
2nd gear @ 5500 RPM = 63 mph
3rd gear @ 5500 RPM = 84 mph
4th gear @ 5500 RPM = 103 mph
5th gear @ 5500 RPM = 128 mph

didn't do a 6th gear speed run, but the gearing is such that
6th gear @ 5500 RPM would = 146 MPH. Mine is not capable of getting to 146 as it is drag limited way less than that
