If you ride by yourself, SG and RG are just a matter of taste. if you have a passenger, look at the Ultra Classic or the Road Kings. If you want to stick with the first two, Harley has seats, tour packs that you can fit. Might run up the cost unfortunately. I have the Ultra, detached the tour pack and put a back rest. For the 07, I had to purchase two docking kits, newer bikes only have one. Might get a solo seat later.
