Honda CB 400 N

The CB 400 N is the name of a series of motorcycle models from the Japanese manufacturer Honda .

In 1978, Honda replaced the models of the 250/400 T series that had just been released a year earlier with the stylistically revised (new) two-cylinder models 250/400 N , also with two cylinders. The Euro look introduced with it was intended to emphasize the relationship to the larger-capacity four-cylinder Honda CB 900 Bol d'Or . The internal model designation CB400T was retained, however, only the sales name was in 400 N CB changed. The CB400N model is closely related to the CB250N, so Honda published some of the same manuals.

The Honda CB 400 N must not be confused with the older, small four-cylinder Honda CB 400 Four with the same displacement . Older CB 400 N models have a single brake disc at the front, younger models have a double disc brake at the front, and all of them have a drum brake on the rear wheel . With its five-speed gearbox (older models) or six-speed gearbox (younger models), it is still considered economical and suitable as a beginner's machine.

The CB 400 N has 32 kW (43 PS) unthrottled, but in Germany, due to the insurance classes, it was mostly offered in a factory-throttled version to 20 kW (27 PS). The throttling is laboriously carried out via the camshaft . There were occasional further reductions to 17 hp, but these were not produced in series by Honda. They were carried out by dealers with accessory parts in a primitive way (narrowing of the intake-side or exhaust-side cross-sections by means of inserted pipe sections) and can usually be recognized by a change in the standard engine performance in the vehicle documents.

In addition to an electric starter, the first models also had a kick starter; this was canceled in 1982.
