The 175 is utterly indestructible! I have actually seen it toured at full throttle for 10-hour days, carrying well over 200 lb payloads by a couple of real big guys who rode them to Sturgis from Minnesota, multiple years. The bikes were so loaded they could just make 85 MPH flat-out, and they never broke a sweat doing it. One of the bikes had over 20k miles on it, the other was about half that, the guys were friends. I saw another one like that during another trip, had over 20k on the clock (but you'd never know it to look at it) in a gas station: the owner was riding coast-to-coast on it again (this was in the 70-75 MPH interstate days prior to 1974 and the 55 MPH speed limit thing) for his second time, and planned a third trip: each one was at a different lattitude, a planned 4th was to be across Canada, he said.
I think they are some of the coolest all-purpose city bikes Honda ever made, myself. I'm not sure I would have the courage (or maybe the butt?) to go coast-to-coast 85 MPH on one, but it would be tempting for 'light touring'...
