In 1949 Giuseppe Benelli quit the eponymous, Pesaro, Italy-based motorcycle dynasty after a disagreement with his five brothers. He quickly set up a new company, “Moto B Pesaro,” in competition with Benelli. His first motorcycles were 2-stroke horizontal singles of 98cc, 114cc and 123cc, but he also built a horizontal parallel twin 200.
Echoing the innovative German-built Imme R100 motorcycle of 1949, Motobi shaped the engine into a smooth “egg” shape, giving it a characteristic styling that Aermacchi would later emulate. The most famous Motobi (as the company became known after 1954) motorcycles were the Catria 125cc and 175cc 4-strokes singles introduced in 1955.
The singles earned a reputation for lively performance, smooth running and a lack of mechanical noise. The 175 proved successful in competition, too, winning nine Italian road race championships in its class between 1959 and 1972.
