The Honda CB400F is a motorcycle produced by Honda from 1975 to 1977. It first appeared at the 1974 Cologne motorcycle show, Intermot, and was dropped from the Honda range in 1978.[3][4]
It had an air-cooled, transverse-mounted 408 cc (24.9 cu in) inline four-cylinder engine with two valves per cylinder operated by a single chain-driven overhead camshaft. Fuelling was provided by four 20 mm Keihin carburettors. The CB400F is commonly known as the Honda 400 Four.[5][6]: 110
