Hi Terry
All my current bikes are 80s Hondas, except '93 NTV 650.
In summer, I happily commute on my XBR, it's a nice way to get to work, skinny, not tiring, and cheapish to run. However, it has 22k miles and good history, and is not concourse. I would worry about winter salt.
I have done 350mile Mway days, more confy for me than the ntv. My wife is a bit bigger than me (I am built like a drink of water) so it's 2-up for short trips but not touring.
Usual 80s Honda reliable, bar what others have said - main factor is previous owner and mileage. Still seem to be a few about, and I suspect most UK ones are connected to this site. Look after oil level and freshness as always.
Exhausts are another hens teeth part...£3-500 for new system, and sometimes doesn't fit centre stand.
I run higher bars (CBX 550 I think, fit straight on, can get away with original cables and brake lines if you raise headlight). Only problem I have had was wheel corrosion internally, caused by leaving Ultraseal in long-term I believe. Now have tube in rear tyre.
No depreciation. Enjoy it!
