Time caps present their own problem because you don't get rid of the cb750 (1969) or the kawasaki h1 and h1r (1969). Plus, since the cb750 stayed the same through out the model run does that mean I could run my 70 or 73 or 75? Personally, vintage is 1975 to me (30 years), but hey it is your class. I'm all for it I'm just trying to get a good idea about it. Personally a no holds barred vintage class limited to the 60's would be nothing but brit bikes because there really isn;t anything big enough to battle the 650 triumphs and 750 nortons until the japs got their shit together. plus jap bikes are 1/4 the money to build a race bike and the jap parts are more readily interchangible with the older bikes making it cheaper to build a no holds barred bike.quote:
Geeto...I mean real vintage...GP class, 1969 at the latest.
I'd allow period aftermarket frame or hand made equivilant. This class would not be about easy or cheap. Probably a 500cc cap on displacement. Ala GP of the period.
