at 19 I bought a KE 175 off a friend and tried teaching myself on a busy city street. No driver's license and no previous experience other than having an Evel Knievel stunt cycle
when I was 10.
Several wheelies and front brake locks later, I put the bike in storage and then sold it to someone else.
When I was 20, I took Quebec's mandatory motorcycle training, which at the time involved 8 hours of classroom and four days of practical. Did the whole course on a virago 250 and did the licensing test on a school goldwing
