HONDA CB400N (1979-1980) Specs, Performance & Photos

In 1980, the Japanese motorcycle manufacturer launched the Honda CB400N, a motorcycle part of the CB series in Honda's range built from 1978 to 1986. At the time, the CB400N was also available in a smaller 250cc version that complied with the licensing regulations in the UK.

The CB400N had almost the same look as the smaller 250cc version but different with its larger engine capacity, twin disc brake on the front, a halogen headlight, and the instrument cluster that featured different markings on the speedometer and rev counter that indicated the higher top speed and lower rpm.

In addition, the bike came with standard features, such as five-spoke cast aluminum wheels, a single seat with two-up capabilities, a wide handlebar, an analog instrument cluster, a black-finished steel frame, and a chromed dual exhaust system.

For suspension, the bike packed a telescopic fork on the front and two EVO shock absorbers with five-way spring preload adjustment 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.

As for the power generator, the 1980 Honda CB400N took its muscles from a 395cc four-stroke parallel twin air-cooled engine fueled by two Keihin carburetors and delivered an output power of 43 hp with maximum strength at 9,500 rpm and 33 Nm (24 lb-ft) of torque available at 8,000 rpm.
