The Honda CB400 Super Four is a CB series 399 cc (24.3 cu in) standard motorcycle produced by Honda at the Kumamoto plant from 1992 to 2022. The CB400 embodies the typical Universal Japanese Motorcycle produced through the 1970s, updated with modern technology. To this end, the bike has a naked retro design, paired with a smooth inline-four engine. Originally a Japan-only bike, it was later also available in SE Asia, and from 2008 in Australia.
