This unleashed new and potent market forces into AMA racing. American riders had demanded more-powerful bikes every year since the end of World War II, and in 1969, Honda and Triumph/BSA raised the ante with the CB750 Four and 750 Triples based on Triumph’s already proven 500. The history of this Triple was much older. In 1960, the designer of the original Speed Twin of 1937, Edward Turner, authored an ominous report on his trip to Japan: Ultramodern production techniques stood ready to dominate motorcycling’s future. As early as 1948, designer Bert Hopwood had explored modular design, a “means of producing a range of machines, from small to large, with as many common components as possible.” Had this been adopted, the results might have been a 250 Single, 500 Twin, 750 Triple, and a 1,000cc Four. Britain instead stuck with steady growth, of displacement and vibration, in its existing Twins—until the Triple.
