You never want to see your bike again after you sell it. Nobody takes care of it like you did.
I traded my second bike, a '77 Suzuki GS400 in on a new GS650 in '81 at the dealer in a college town. It got sold to a guy in a frat. I think he let everybody ride it.
Next time I saw it 2 weeks later both sides of the tank were smashed in and the instruments were busted. Never saw it again until 5 years later rusting away at a motorcycle junkyard. It only had 600 more miles on it than when I sold it.
