Unsatisfied with CB450 sales in America, Yoshiro Harada, who was in charge of CB450 development, took a trip to US. Around summer 1967 Harada arrived in US and studied the CB450's impact in local market. He found that American love bigger engine. So he decided to develop a 750cc motorcycle with 4 cylinder inline, bigger horsepower (67 horsepower). Honda is aiming for performance and safety at the time, disk brakes Harada brought from US implemented in brand new CB750. This never done before, so CB750 is the first motorcycle to use disk brakes in the world.

CB750 was such a huge boom in US, and led to the new category "Nanahan"
Nanahan: Meaning 750 in Japanese, the term was used by the development staff to maintain the confidentiality of their new model. Nanahan later became a popular term, and was widely used in magazine circles.
