My
North Georgia Mountains Trip was one of these loops. We bailed about 3/4 the way through because my wife was getting bored. It is also a big road cycling (pedal kind) loop also. Bicyclistis call it '6 Gap' And it is a bit simplified. I have done it a dozen times or so. And ridden modified (3 or 4 or 5 gap) parts of it probably 50 or so times.
Motorbike Ride : Dahlonega - Suches - Helen ( North Georgia 8 Loop )
I highly recommend. It should be doable from North Metro Atlanta on a single range charge in decent weather. It is probably 240 or so miles to get there drive the full loop and drive back.
