Central Motor Vehicle Co., Ltd., Tokyo, 1954-55
中央自動 車 株 式 会 社
Central sold a clip on engine for mounting on a bicycle frame, which was called the Kitty (キティー号), although on the engine case it does say Baby Kitty. In 1954 it was a 60cc engine, and for some reason in 1955 was changed to be a 50cc engine.
