I haven’t installed a back rest yet on my 2021 RT Limited. Like you, i thought about installing one (Utopia) but that’s as far as it got (thinking about buying one). Instead, i figured I’d ride it for a spell just to see if i really needed one. So far I haven’t found the need for an additional back rest. I say additional because, the OEM saddle on my Spyder offers a generous amount of lower lumbar support, and although a little more support above the stock saddle would seem to be a welcomed addition, i just haven’t felt the need to add a back rest yet. My advice to you is wait a bit, put some time in your current saddle and see after a bit if you feel its needed
That said, I’m not trying to talk you out of installing a back rest rather, all I’m saying is give it some time riding w/o, before investing in one. I’ve used back rests on several motorbikes through the years and before you ask, yes!, i have constant lower back issues yet on this Spyder, so far, i just haven’t felt the need for fitting one yet
I should mention, all of my riding on this RT to date has been local riding, no long distance saddle time yet. I have a birthday coming up middle of next month and if I can get away, I’d like to ride down to Key West and look up some old friends. If i can swing this little excursion and feel the need for some more support on my back side, I’ll come back to your thread here and say whether I found a need to add additional back support
Best,
