Osaka Zet Industrial Co., Ltd. (Kita Ward, Osaka City)
Osaka Zet Industrial made the 'Z' line of motorcycles. Very little other information is available, other than in the 1953 model year they offered a 90cc, 150cc and 200cc range. It is unlikely they made their own engines, and it is not known what years they were in business for, other than 1953. There is a note on the Yaplog web site that they appeared in the Nagoya T · T race and placed 9th and 13th.
Plunger suspension at the rear, wet sump ohv 4 stroke engine, with coil ignition and a 2 speed gear box.
