Moreover, although it is a high-performance vehicle, it is easy to handle and has excellent steering stability.

1969 Honda Dream CB750 FOUR History

Honda started exporting this model mainly to the United States and Canada in spring 1969. At that time in the United States, there has been a growing tendency to love motorcycle sports and enjoy leisure, and it has been extremely popular. Honda have decided to start domestic sales also in response to the strong demand.

At that time, reliable information came in that British company Triumph was developing a high-performance 3-cylinder 750cc motorbike. This was the impetus for the concept of a large motorcycle with a 750cc engine and an output of 67 horsepower (because the Harley's 1300cc was 66 horsepower, the idea was that it would be better if it exceeded 1 horsepower), in October 1967.

About 20 people started a development project in February 1968, and began designing the CB750FOUR. At that time, Honda was the world's largest manufacturer of motorcycles due to the explosive popularity of the Super Cub.
Rivals of the CB750FOUR were Triumph, BMW, Harley, etc., and it was necessary to ensure performance and reliability that could compete with them.

Therefore, the engine structure of 4 cylinders and 4 mufflers, which immediately makes you feel that it is a direct descendant of a Grand Prix machine, is the keynote, and by tailoring it to an up-handle that Americans like, it pushes a wild and dynamic image to the fore. . It was also the first large-displacement vehicle, and was equipped with technology that fully considered mass production and maintainability.

The basic development plan was not only to improve the output characteristics, but also to make the continuous high-speed long-distance touring on the highway safer and more comfortable.

With Honda's success, other Japanese manufacturers followed suit in the 750cc large-displacement sports bike category, sparking the so-called Nanahan boom. It is no exaggeration to say that the CB750FOUR has created a genre called Nanahan.
