looks like it WAS raced.. no tags, no blinkers.. it has a glass headlight though.. maybe that was done later?.. those wheels aren't 72 either
actually, looks like someone had a tag mounted on the back of the tail.. see the holes?
that's a disc rear too, someone was uprating that thing as he was going along.. someone loved that bike..
I wonder what the big front wheel did back in the day? stability?
its kinda weird looking back in time like that... the original owner is probably dead by now..or in his 70s
