Under development for one year, when finally introduced to the market, The CB750 offered two unprecedented features: its disc brake and its inline four cylinder engine -- neither of which were previously available on mainstream, affordable, production bikes. These two features, along with the bike's introductory price of $1495.00 (US), gave the CB750 considerable advantage over its competition, particularly its British rivals.

''Cycle Magazine'' called the CB750 "the most sophisticated production bike ever" upon its introduction. ''Cycle World'' called the motorcycle a masterpiece, highlighting Honda's painstaking durability testing, the bike's 120mph top speed, the fade-free performance of the braking, the comfortable ride, and excellent instrumentation .

Cycle World called the motorcycle a masterpiece, highlighting Honda's painstaking durability testing, the bike's 120mph top speed, the fade-free performance of the braking, the comfortable ride, and excellent instrumentation .


As the first modern four cylinder machine from a mainstream manufacturer, the term Superbike was coined to describe the CB750. The bike offered other important features, both great and small that added to its compelling value: electric starter, kill switch, dual mirrors, flashing turn signals, screw on oil filter, maintenance free valves and overall smoothness and freedom from vibration both underway and at a standstill. On the other hand, the bike was difficult to get on its center stand and tended to throw chain oil on its muffler.
