The CB450SC Nighthawk launched in 1982 as Honda's US-market styled standard, using the 447 cc three-valve twin with a six-speed gearbox, a stepped seat, a 16-inch rear wheel and Comstar wheels in its first year. It was praised as an affordable, comfortable all-rounder and stayed in the range until 1986 with mainly cosmetic changes.
