In 1982, the Japanese motorcycle manufacturer launched the Honda CB400N, a motorcycle part of the CB series in Honda's range built from 1978 to 1986, designed as an agile and versatile middle-class naked machine that suited a wide variety of riders.

At the time, the CB400N was also available in a smaller 250cc version that complied with the licensing regulations in Uk that was also the most popular selling bike in the UK market, with over 17,000 units sold only in 1980.

The CB400N featured almost the same look as the 250N version but differed in other departments, such as the larger capacity engine, dual front brake discs, a halogen headlight, and the instrument panel that featured different markings for the rev counter and speedometer, which reflected the higher top speed and lower rpm redline.

In the performance department, the 1982 Honda CB400N had its soul brought to life by a 395cc four-stroke parallel twin air-cooled engine fed by two Keihin carburetors that helped deliver an output power of 43 hp at 9,500 rpm and 33 Nm (24 lb-ft) of torque available at 8,000 rpm.

For suspension, the bike packed a telescopic fork on the front and dual EVO shock absorbers with five-way spring preload adjustability on the rear, while the braking performance was handled by two 239 mm discs with hydraulic calipers on the front wheel and a 152 mm drum unit on the rear wheel.
