HONDA and DREAM CB750FOUR (Doremushebe ..floatage.. Foix) are motorcycles to which Honda Motor Co., Ltd. was doing the manufacturing sales.
Details until developing

At first, the reputation in foreign countries was not fragrant though HONDA that accomplished complete conquest by the road racing world championship at that time aimed to advance worldwide on a commercial side, and announced and had exported the new car of dream CB450 etc. one after another except the desire. It is because there was respect that lacks from a room that the rider can manipulate even if the performance is put out by a small displacement little to easiness to get on because this values a top speed of the motorcycle as a flow from the race.

Then, all technologies at that time will be concentrated on manufacturing as a motorcycle at that time because it becomes a maximum level displacement though the vehicle that can correspond also to a recent race standard after coexisting of the performance and room is attempted because of the expansion of the displacement is planned and production was decided.

The vehicle manufactured thus is dream CB750FOUR (henceforth CB). The dream of the car name is a series trademark that HONDA was using for the efficient at that time, sports type.
The main equipment and performance of CB

Engine Parallel four cycle four cylinders OHC
The cylinder is narrowed a little by using a lot of parts of aluminum and width and the weight of the engine are suppressed though the engine adopted four parallel cylinder engine of two-wheel mass production first car considering externals. About the Shaiki valve, not DOHC but easiness to get on and productivity for the high rotation used from the low rotation were considered to a racer at that time, and ..daring.. SOHC was adopted. As two-wheel mass production car, it is the first time to have equipped four cylinders all with the carburetor.
Engine performance- 738cc･67 horsepower and maximum speed 200 km/h
The displacement and the horsepower of the engine were decided in shape to compare engines of this industry and others car. The performance that it is possible that it put on the speed at 200 km/h was still secured though it was suppressed from the priority of easiness to get on to the output extent more than the highest all motorcycles on the market, at that time, value though it was also possible that this engine raised the performance a little more. However, this is called the purpose is for the parts supplier to clarify the responsibility to the manufacturing thing to HONDA though parts only for CB will be both made as for a tire at that time and the chain because it is not possible to finish corresponding to this horsepower, and the explosion and the plasmotomy were repeated while developing.
Front wheel disk brake
The manufacturer named the MV Agusta had already used a small amount of front wheel disk brake in the production vehicle. However, it has been decided to make it equip with the disk brake by "Authoritative word" of Soichiro Honda who is finally the president and exhibit though the comparison discussion was done which the drum or the disk to be used just before Motor Show to which a real car of CB is exhibited because it was unexampled in two-wheel mass production car. As a result, it is told that it had a hard time in the accumulation of knowhow though the disk brake will be adopted for the first time as two-wheel mass production car. It is true that working of the brake worsens extremely when the rain running.
