I agree with Stan, the bikes that we owned in the sixties and 70`s they should have been parked in dry storage,, for etc F21m,69 Montesa cappra 360, Mag Husky 74 model, my 3 Honda elsinore, Norton TQ 850, Jap speedway bikes, my fathers 6 scotts, and the list go`s on, and in the same time, running around every bike shop in Melborne asking and buying up old bikes. But in saying all that, back in the those days we didn`t have a lot money to buy bikes,plus it wasn`t top on our list, we didn`t think to do it, just looking forward to the next race meeting, it was a big effort to save, and price money wasn`t the big, it all went into fuel and food on the way home. The B50`s are a great bike Greame, you need to ask someone at a meeting and go and ride one. You will love it.
