When was the last Honda 400 four motorcycle made?

Answer 1

Of the 400cc motorcycles produced by Honda, the Honda CB400F is perhaps best known. This bike has an inline four engine and was produced from 1975 to the end of 1977. The concept of light four cylinder engines in sizes between 350 cc and 500 cc was new in the seventies. After a few years of producing these bikes, Honda started to emphasize bikes with larger four cylinder engines and twin engines, the latter having a displacement from 400 to 600 cc and larger. Of the light four cylinder bikes, Honda produced the CB350 Four, the CB500 Four and the CB400F with a 408 cc engine (in two verions). Basically, the CB400F was an upgraded version of the CB 350 bike. The CB400F had an eye catching exhaust system of four-into-one winding around one side of the bike frame. This bike had a racer-like appearance, considering the angular and rather flat fuel tank and the cafe-racer style handlebars, much in contrast to the CB350. The CB400 could not compete in acceleration with bikes that had three-cylinder two-stroke engines in similar sizes, such as produced by Kawasaki at this time. However, a six-gear transmission increased the top speed of the bike. The CB400F was known as a bike of precise engineering and nice workmanship and was popular with many people. The 408 cc engine was upgraded and bored out to 490 cc by some race drivers. This greatly increased the power and top speed of the bike.
