As crazy as this sounds, my back feels better when I get off my Sportster after 200 miles than when I got on it at the beginning of the trip.
By the time we are all 40 or 50 years old we have back problems, even if we can't feel them. So many issue contribute to rider comfort or pain and they are so specific to the individual rider that they can be hard to address.
For you, the good news is that your back issues do not crop up on all motorcycles, which is often the case for most riders with back problems. In your case, I think that I would whip out the old tape measure and draw diagram of the basic cockpit dimensions on each bike. You are primarily interested in distance and angle to the bars from the back of the seat. Seat height relative to the bars, seat to the controls, etc.
What you want to do is to find out where the Harley is different from the Triumph. Are your legs stretched out too far on the Harley, or are the cramped. Are you having to reach for the handelbars or are you riding with your weight being supported by your wrists, arms, and back instead of in a more upright riding position?
An almost universal solution for riders with lower back problems is to buy a seat, [Mustang makes some great seats], that has a backrest. Of all the attempts to fix lower back issues, the most successful one is the seat with a backrest. I know riders who would quit riding if they could not have a backrest.
