The CBX400F was Honda's answer to the Japanese 400 four boom and the spiritual successor to the cult CB400F, with a 16-valve DOHC engine, six-speed box, Pro-Link single-shock rear on a hollow aluminium swingarm and enclosed inboard disc brakes. It was sold only in Japan, where American testers lamented it was not offered in the US.
