I am old enough to remember the Honda CB750/4 being introduced!
Here is a tribute that bike:

I have a few problems with it:
1) It's water cooled
2) It's not a 750cc
3) It looks nothing like a CB750
4) It doesn't have 4 exhausts
In fact, other than wire wheels and the Honda nameplate, I see no resemblance to a CB750 whatsoever.
Don't look too closely at the front wheel/brake caliper/disk it looks like an Escher drawing and makes your eyes go funny.
