The CB400N Super Dream replaced the short-lived CB400T Dream in 1978 with sharper Eurostyle bodywork: a long slim tank that flowed into the tail, new silencers and paint. Underneath it gained twin front discs, a six-speed gearbox, stiffer fork springs, a better-supported swingarm pivot and revised cam timing and carburation. It became one of Britain's best-selling middleweights, sold in Japan as the Hawk III.
