I'm in a similar boat as you, except:
1. I'm not as old, but almost, and I'm retired
2. Rode large touring bikes for many years (but I'm keeping my 2017 Electra Glide)
You are right about higher interest rates slowing sales. It ain't just happening with HD motorcycles. Cars and trucks aren't moving as fast either. Prices on those are dropping as well.
I say the PA was brought to market to attract younger buyers because HD at the time said they were doing that (not my opinion, theirs), and had plans to bring out several other models to attract younger buyers around that same time, including a sport streetbike called the "Streetfighter" (that never actually made it to market). Remember that? The Livewire EV was a younger-crowd product as well. I think HD may have underestimated the appeal some of these models may have had with traditional HD buyers, but lucky for HD.....the traditional HD buyers are helping with their sales of those models.
