I bought a 2023 Nightster, and I love it.
I traded an old amd cantankerous DR650 and a nice 750 Street Rod in on this. The SR was starting to need some parts, and it was going to be a long time before I was able to get them. So I had two bikes, one which needed a belt and fork seals (which I couldn't get unless I waited) and another that I could get parts for, but I was constantly having to fix.
Now I have one nice bike I can actually ride. It's smooth, quiet, fast, and reasonably comfortable. I've never had traction control or ABS brakes before, that may take some getting used to. The bike is so effortless to ride. It's nimble, its fairly light for a cruiser. (and it's feather-weight compared to any other harley) The suspension soaks up the bumps, and I've never ridden anything that felt so firmly planted on the road. It has a 975cc engine that sounds nothing like a "typical harley", but it still sounds good. Here's hoping I don't have the only one left four years from now, like what happened to my Street Rod.
It's right in the specs.
Edit: Oh, you mean on the bike. I see.
That's literally the only place I've seen the displacement shown in ci. On the manual, the paperwork, the title, and the actual machine its an RH975.
Sportsters have been showing their displacement in cc's for decades. There's an 883 and a 1200.
