All GB500/400's featured black-green paint with gold pin-striping and lettering, as well as chrome wire wheels, , steel-braided oil lines, steel side covers (i.e., not plastic), round gauges with matte silver faces, fork gaiters, non-adjustable fork with hydraulic damping, 18-inch wheels with tube-type tires, solo seat with painted rear cowling and a fuel tank indented with knee grips. The GB500/400's engine was based on the Honda XL600 engine, a four-stroke . The four-valve single cylinder engine featured a radial four-valve combustion chamber, along with a tubular frame, wire wheels, clip-on handlebars, solo seat, seat hump, and pin-striped gas tank. The styling resembled TT single-cylinder racing bikes (such as the Manx Norton, the and the) that were prominent in the TT until the 1960s. In the USA, GB500s were imported for model years 1989 and 1990. In 1992, a third-party exported 1,000 unsold Honda GB 500 Clubmans

(German) from the USA to Germany as grey import vehicles. Both the 400 cc and 500 cc versions were imported and sold by Honda New Zealand. When originally released in NZ, the GB came in three models: dual seat; Mk2 with half-fairing, single seat with cowling; and no fairing, single seat.
