Despite having taken the 1983 500cc Road Racing World Championship Grand Prix Riders’ Championship (their first since 1967) on the 2-stroke V3 engine NS500, Honda were not satisfied with their motor and felt that more power would be required. Thus, the Japanese motorcycle giant came up with a single-crankshaft V4 design engine which was used in their 1984 entry. It featured a unique aluminum frame to house the engine and a radical layout in which the expansion chambers and the fuel tank were positioned above and below the engine respectively. The bike would go on to compete in road races over the next 19 years, and now appears as a 1/12 scale model in the Tamiya line-up.
