Launched in 1969, Honda's first four-cylinder roadster revolutionized the motorcycle market, setting new standards of sophistication, user-friendliness and reliable high performance. The innovative CB750, with its SOHC engine, five-speed gearbox and disc front brake, changed the face of recreational motorcycling worldwide.

In 1977 Honda reintroduced the CB750K7 and CB750K8 when customers decided they did not like the CB750F1 or CB750F2.
