Summer of '67 I was 15 with a learner permit. We were allowed to ride a motorcycle without passenger. I bought a '51 Pan Head with mousetrap, gold metalflake sportster tanke (2.2 gal) ribbed rear fende, bates seat, flanders #0 bars and a sissy bar about 10 inches high. It had 4" over forks. It cost $150.00 US.
it was a day, maybe two, later; It got away from me. bent the forks under hitting an exceptionally tall curb and at a somewhat less than prudent speed. I got a '59 BSA road rocket after that. Kept that bike for a couple years.
