The Honda CBR400 is a Japanese domestic market small-capacity sport motorcycle, part of the CBR series introduced by Honda in 1983. It was the first Honda motorcycle to wear a CBR badge.

The CBR400R (NC17) naked bike was launched in December 1983. The 4-valves per cylinder, air-cooled, four-stroke, DOHC, inline-four engine has a rotational-speed valve stop mechanism "REV" (a prototype of Honda's VTEC system) that changed from two valves into four valves at 9,500 rpm.[citation needed] The following two years, it came as semi- and fully faired version as the F3 Endurance.[citation needed] The CBR400R and early CBR400RR models both carry the model number NC23, which makes up the first part of these bikes' frame numbers.[citation needed] In 1986 the CBR400R was also known as Aero, Jellymould, as it shares its major design features with the rest of the early CBR600F and CBR1000F Hurricane family of motorcycles,[2] which include significantly rounded body shapes. Whereas the later 1988 model was designated CBR400RR and was also known as the Tri-Arm,[2] after its racing inspired braced swingarm.[citation needed]

The original CBR400F as a naked bike

The CBR400RR in 1992 was referred to as the 'Baby Blade' replica, then in 1994 it was styled to closely look like the CBR900RR or Fireblade motorcycle.[2] Though over the years, in performance and handling, it was more closely compared to the CBR600.[2] The CBR400RR preceded the 900 cc (55 cu in) Fireblade by four model years, going through one major rework (signified by a new "gull-arm" swingarm design).

The CBR400RR models are the NC23 and NC29 CBR400RR-J (1988), CBR400RR-K (1989), CBR400RR-L (1990–1991), CBR400RR-N (1992–1993) and CBR400RR-R (1994).[3] The name "Tri-Arm" is shown on the CBR400RR-J's bodywork, along with Hurricane, but the CBR400RR-K dropped the latter designation.[4]

The NC23 CBR400RR features a standard extruded beam frame, the rear of the seat unit slopes forwards, and the seat unit subframe is totally separate from the main chassis of the bike. The NC23 & NC29 (only the -R models of which carry the FireBlade name) have several modifications to the frame.[citation needed] The main rails are of a 'cranked' design, the seat support structure has a larger rail that was welded to the frame, the rear of the tail section now had a slight recurve to it, and the swingarm was given a gull-wing shape on one side to give ground clearance for the exhaust link pipe.[citation needed]

In 1985, Honda brought a CBR400F to the US for testing, on which Cycle World recorded a 0 to 1⁄4 mi (0.00 to 0.40 km) time of 13.63 seconds at 95.94 mph (154.40 km/h) and a top speed of 179 km/h (111 mph).[1]

In 2013, Honda released the new twin-cylinder CBR400R along with its naked model, the CB400F (not to be confused with four-cylinder CB400 Super Four), and sport adventure model, the CB400X, which is based on the CBR500R, CB500F, and CB500X respectively. These models are sold in Japan & Singapore only.[5]

New generation features
