Nice UJM collection!
Seeing these bikes really takes me back.
That 550 four is the bomb!
I remember riding home this kid's bike just like that one from high school. He was kind of a wuss and he low speed dumped in the parking lot (not a scratch) and was too shook up to ride home!
So I volunteered to ride it to his house. I couldn't get over how smooth it was compared to my CB 450 twin.
