context_page_description: 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.
  It had an air-cooled, transverse-mounted 408 cc 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.
context_section_description: The CB400F was produced in three variants during its production cycle; the F, F1 and F2.
  1975: Launch model had swingarm-mounted passenger footpegs and was available in Light Ruby Red or Varnish Blue.
  1976: Passenger footpegs were moved to a loop off of the rear subframe. It also gained a lock for the fuel filler cap.
  1977: F1 model released as a US and Canadian-only model, with few bikes coming over to the United Kingdom. It had higher bars and footrests repositioned further forward to cater to consumer demand.
  1978: F2 model was virtually the same as the earlier F model except for a minor restyled fuel tank and decal changes. This variant was available in Candy Antares Red and Parakeet Yellow. American F2 bikes had black side covers. Longer cylinder head studs were fitted after engine number 1084315 to try to remedy the problem oil weeping from the head gasket.
  To comply with licence restrictions in France and Japan, Honda also produced a 398 cc (24.3 cu in) version by fitting a shorter 48.8 mm (1.92 in) stroke crankshaft.
