Starting with the CB750, Honda redefined what a motorcycle should be. The other Japanese manufacturers followed Honda’s lead, resulting in the UJM, or “Universal Japanese Motorcycle.” This left its mark on the motorcycle industry, which has never been the same since.
Ultimate Motorcycling has a great article on the history of Honda’s inline-four bikes, starting with the iconic CB750. While my own 1981 model was no longer the barnstormer the original was, it was still a fun bike, and just what I needed at the time. Truth be told, I originally wanted the Magna parked next to it, but after seeing it was smashed down the left side, my eye moved to the CB750 Custom parked next to it. I have no regrets (though I still want a Magna someday).
