Not since it’s release at the Tokyo Show, Japan, in 1968 has any motorcycle to this date, caused such a sensation around the world. The Honda CB750 (Four) was finally released in 1969 to the public and immediately set new standards of performance and reliability.
The CB750 was the worlds first mass produced four cylinder bike, which also incorporated, electric start, four carburettors, five speed gearbox and front disc brake. From its release in 1969, the CB750 (KO to K4) dominated sales right throughout the early 1970’s and it was not until the release of newer rivals that Honda decided to give the bike a facelift.
In 1975, to combat their rivals, Honda released the CB750 F1, ‘‘Supersport’. The F1 had minor alterations to its engine to reduce emissions and was fitted with a rear disc brake and 4 into 1 exhaust to further enhance its stylish new appearance.
In 1977, the vivid yellow F1’s were updated to the CB750F2. The F2’s had major design changes to the frame, front forks, twin front disc brake, cylinder head, exhaust, and finally ‘Comstar’ wheels.
Finally, in 1979, after 10 years of production of the CB750 KO to F2, Honda released the new DOHC, 16 valve, CB750K which saw the demise of the original CB750 SOHC engines. The new bikes suffered badly from unreliable engines, poor handling and diminished sales, all which seemed like a world away from the original brilliance of the original CB750 (Four)
Even by today’s standards of engineering and technology, the Honda CB750 (Four) released in 1969 through to 1979 will always be regarded as the world’s first true “Superbike”.
