I find I'll manage much longer in the saddle, but that is only possible because of an upright sitting stance with hollow back. I have to do that in any case, because of my back problems.
The way I have achieved this on my current ride, XV1900A (Strat/Roadliner), is by adding risers, with a few inches extra of pullback. On my previous ride, XVS1300A (V-Star 1300), I exchanged the standard handlebar for a touring bar, to achieve the same. This also allows me to take up varying riding positions, if I feel like doing so. Prior to adding the extra pullback, I was forced to sit bent forwards, in one postion only, and that generally just kills my back. Now I ride in comfort, and it actually is having a beneficial effect on my back - when in pain, go for a ride, and all will be well again for a few hours up to a few days even.
Having said all this, I would like to get a more comfortable saddle for sure, ideally one which is padded, and which provides space for the tail bone, so it doesn't bear all the weight. I am a bit worried that neither the Ultimate, Mustang, or Corbin saddles provide this however. I'd love to hear if there are other solutions for a saddle providing this kind of extra comfort
Kind regards, Wim
