I'm 47. Some of my bikes are that old or a little older ('65 CB77, '66 Ducati Monza 250, '67 CB77, 2x '67 CB160, '67 CL160, and '68 CL175).
My main CB is a '76 CB400F.
The all the 67's listed above are projects, the '68 CL175 is a nice rider, and the '65 CB77 is a deal just made, but, haven't collected yet.
