I'm a huge fan of the early enduros as my first one was a 1969 CT1. My first MX race was on that bike after my Dad and I "fixed it up" with a hooker pipe a 21 inch front wheel, preston petty front fender and of course stripped it down. Wish I had all the original parts now as I currenty own 4 of them. 1 is pretty decent and it is a 1970 model. Have 2 real nice recent purchases from Bring a Trailer and they are a 1970 AT1 and a 1971 DT1.
