Started on a Yamaha DT175, 1975 I think. I was 15 and crashed it on the test drive and bought it out of necessity !! Broke the bars, levers etc. walked it back to the owner and said i'd take it. I remember thinking this was the fastest thing on the planet ! "look Mom, new toy and new scrapes & bruises" She was one happy camper ! Young, stupid, ignorant - I heard them all, and have to agree !
