6'3" here and very comfortable on a Road King. No wrong choices among these three as for fit. Buy the one that plants a smile on your face.

 

I went from a RK to a SG and back to a RKC. I really missed my RK because to me it is the smoothest of all the touring models and the versatility of the bike. Coming from a non fairing bike, you may or may not find it easy to get use to. By the way I ride at least 15K a year touring and I am going on 63. Good luck on your decision.

 

This is VERY true...strong cross winds will have you leaning into the wind with the Road Glide, but if you go faster, it gets easier to get through it (don't ask me how I know...)

 

Ditto and ditto - Love my RK - I'm 63 as well -

They are all good choices but as for me it's RK
