I'd solidly advise going with the Road King. You'll find it handles much more like a sport bike than it appears it would. The '09+ touring bikes are orgasmic to ride through the twisties. I've got one now. I had an '07 Road King and thought it handled well, but there's a real difference for the better with the new chassis configuration.... I'm toying with the idea of jumping onto a Harley. ... 2 models that have caught my attention are the Road King and the Fat Boy.
As an owner of bioth a touring bike and a FB. I find it strange picking between the two.
They are from different worlds. Kind of like comong to a stop sign and asking do I got right or left.
A FB is never going to give the ride a touring bike will and that is even a bigger issue if you go two up.
A touring bike will never give you the feel of a softail they are just plain fun to ride IMO.
Wait till you are sure buying the wrong HD is painfull to the pocket book.
