Recommend a HD for someone with back problem
Guess i would ask what type of riding do you want to do. Just local here and there or you want to do alot of long long trips.
If i was just buying a HD to ride around locally with maybe only a big trip every cpl years then probably go with the dyna or softail with best seat i could find and a back rest.
If i were planning to ride till i cant walk and tour the country then id get the ultra and have it all
Like a previous poster, I had an L4/L5 problem (the most common injury for computer programmers -- more common than carpal tunnel.) Mine was treated with a lumbar disc excision instead of fusion. For me, the problem is in myself and not my bike -- a backrest didn't help. It felt comfy, but it encouraged me to slouch and so road shocks (expansion joints, potholes, etc.) hurt. In the end I had to pay attention to my posture when riding and spend a lot of time at the gym strengthening my back and abs. Pro'y not the answer you want to hear, but I can ride 18 hours without pain, get up the next morning and do it again.
1. Backrest. (I have a Mustang Solo seat w/ backrest and a Harley backrest for my Sundowner seat.) The backrest has done wonders & is easily the best "investment" to date as far as helping my back. I'm sure you realize that having no support to your lower back while holding your upper body up on a vibrating, moving machine is a recipe for fatigued, sore back muscles. The backrest gives the support I need, so I am pretty sure I'll never be w/o one, at least for rides over an hour. That means my Badlander seat, which I love the looks of, will be a dust collector.
2. Back-a-Line belt (google it...saw it on webBikeWorld review site). This did/does pretty good. Did a "patch run" one Saturday with this. No sore back while wearing it. Took it off the last 15 minutes and back started hurting. It's not "Harley chic", but hey...it may keep ya riding! I haven't used it since the backrest, but will take it on long trips just in case.
3. Advil, Tylenol, Advil, Tylenol. I say this as kind of a joke, but not really. My spine surgeon said alternating these OTC drugs works well for back pain. Something about them working together well.
4. Stretching, Core Strengthening exercises, keeping your weight down. Yeah, I know...know I'm starting to sound like your mother/wife/doctor/girl friend, etc. It sucks, but trust me, all that stuff really helps the old back. Betcha didn't think you'd hear those suggestions on the HDForums!

4. As far as bikes...like someone said...try them out. My bike vibrates like mad while idling, but smooths out once I get going, so don't let a Road King turn you off. I'd stay away from a pre-2000 year model bikes as they vibrate more. I also imagine any bike that's slammed will hurt you (think bumps). Consider the shocks, tires, suspension, etc (talk to the dealer). The stiffer bikes will transmit more energy into your body/back. The touring models may be the way to go with the air suspension. I know my RKC is a much comfier ride than my buddies '03 Fatboy. (to the previous poster w/ the '03 Fatboy...no bad things to say about the bike...love it, just my friends is lowered and after a 200 mile ride, she was pretty uncomfortable. Good to hear you are fine on yours!)
I know this is a long post...hopefully you'll find something helpful. These guys on this forum should provide you with a lot of great advice.
Good Luck!
