I just sold off my three CB400T Hawks last fall. That was the bike I chose for my son to learn to ride, primarily since I already had them and they are smaller and easier tyo ride. About 200 pounds lighter than the CB750, so they are much more nimble and easier to handle, a bit shorter, with enough power to ride the highway and very nice stoplight to stoplight because of the low end twin torque.
Easy to work on and generally available for a much more reasonable price than the older SOHCs.
My first bike a long time ago was a 1969 Honda 175. I don't remember if it was CB or CL or what. I do know I was a skinny kid, but the wind and the gradient had to be just right for me to cruise at 70.
JMHO.
