I think you’ll find as you ride, that there are those who ride rain and shine every non winter day, and those that ride on the sunny weekends and on the odd nice warm summer evening. Both bikes are well cared for, and well maintained, I think you just are looking at a weekenders bike.
I bought an older bike too, mine was from Kijiji a 1985 honda shadow 750, in amazing shape, but 35,000 miles on it. Very well cared for. I checked mine just like you that it had not been dropped, that the handlebars lined up to a straight steering front wheel, and that all the lights worked. With it’s dual tail pipes I made sure that i felt an equal pressure out of both of them when it was running, (less pressure from one would mean not firing well on one of the cylinders), I checked the tires and fork seals to make sure they weren’t cracked. Then I had a long time motorcycle rider take it for a spin, testing the brakes and steering and the gears. I got a green light so I bought it.
I’ve put 4500 miles on mine in my first year of owning a motorcycle, rode it till the snow flew, started the first melted day the roads were dry. Think I’ll beat that this year, but I just love being out on the bike. And really no major issues at all with the bike.
