The Honda CB/CBX's,
Honda of Japan introduced the CB750 motorcycle to the US and European markets in 1969 after experiencing success with its smaller motorcycles. The CB750 was targeted directly at the US market after Honda officials, including founder Soichiro Honda, repeatedly met with US dealers and understood the opportunity for a larger bike. In 1967 American Honda's service manager Bob Hansen Mr Honda that he should build a 'King of Motorcycles' and at the Tokyo Show of October 1968 and the Brighton Show of April 1969 the CB750 was launched Under development for a year, the CB750 offered two unprecedented features, a transverse straight-4 engine with a single overhead camshaft (SOHC) and a front disc brake, neither of which was previously available on a mainstream, affordable production motorcycle. Cycle magazine called the CB750 "the most sophisticated production bike ever" on the bike's introduction. Cycle World called it a masterpiece, highlighting Honda's painstaking durability testing, the bike's 120 mph top speed, the fade-free performance of the braking, the comfortable ride and excellent instrumentation.
The CB750 was very successful and was followed by a stream of CB models moving from SOHC to DOHC and then to the 24 valve CBX1000 in 1978, the fastest accelerating machine of its time
