Thoria Motorcycles
Manufactured by the Roelens brothers who ran a bicycle business at Roeselare baan 36 Torhout. In 1947 they produced their first powered machines, 50cc mopeds fitted with the Ducati Cucciolo. These were followed by 98cc and 147cc motorcycles with engines from Sachs, and a 98cc tandem. They also built motorcycle frames for other small manufacturers including Star.
