Itagaki Co. Ltd., 1948-61
Originally the aircraft parts manufacturer Isezaki Aircraft Industry, Itagaki began making bicycle components in 1945. In 1948 it began selling under its subsiduary's Sanki Kogyo Co. Ltd. (三輝工業株式会社) name. The 1954 Sunlight SMR 11 used a Itagaki 2 stroke, 58cc engine in a Sekine bicycle frame.
In 1958 and 1959 the line-up included the Sunlight 125cc King Moped C1, the Million Sunlight C10, Sunlight Royal and Sunlight Queen Mopet. In 1960 was the Queen Sunlight 50cc and Queen Sunlight 125cc.
Although they looked like motorcycles, the 125cc models appear to all have used a centrifugal clutch and a v-belt drive.
In 1961 the company was absorbed into Fuji Heavy Industries and began manufacture of Rabbit scooters.
