Honda CB750 and CR750

The CB750 is an air-cooled, transverse, in-line-four-cylinder-engine motorcycles made by Honda over several generations for year models 1969–2008 with an upright, or standard, riding posture. It is often called the original Universal Japanese Motorcycle (UJM) and also is regarded as the first motorcycle to be called a "superbike". The CR750 is the associated works racer. Though other manufacturers had marketed the transverse, overhead camshaft, inline four-cylinder engine configuration and the layout had been used in racing engines prior to World War II, Honda popularized the configuration with the CB750, and the layout subsequently became the dominant sport bike engine layout. The CB750 is included in the AMA Motorcycle Hall of Fame Classic Bikes; was named in the Discovery Channel's "Greatest Motorbikes Ever"; was in The Art of the Motorcycle exhibition, and is in the UK National Motor Museum. The Society of Automotive Engineers of Japan, Inc. rates the 1969 CB750 as one of the 240 Landmarks of Japanese Automotive Technology. Although the CB750 nameplate has carried on throughout multiple generations, the original CB750 line from 1969 to 1983 was succeeded by the CBX750, which used the CB750 designation for several of its derivatives.
