Rikuo Internal Combustion Company (陸王内燃機関株式会社, Rikuō Nainenkikan Kabushiki kaisha) was one of the first motorcycle manufacturing companies in Japan. In the early 1930s Rikuo operated under the license and name of Harley-Davidson, using their tooling, and later under the name Rikuo until 1958.[2] Harley-Davidson themselves did not publicize this Japanese connection because the Japanese were helped in developing mass-production techniques by the introduction of this factory into Japan just prior to the Second World War.[3] The Society of Automotive Engineers of Japan (in Japanese) rates the 1935 Rikuoh Large Motorcycle as one of their 240 Landmarks of Japanese Automotive Technology.[4]
