About Motobi
Country of Origin:
Italy
Founder:
Giovanni Benelli (Benelli family offshoot)
Best Known For:
Egg-shaped horizontal singles (“Catria”) and light sporting machines
Company History
Motobi split from the Benelli family to pursue compact, horizontal singles housed in elegant pressed-steel frames. The ‘egg’ engine layout saved space and simplified service, while the bikes’ proportions and paintwork made everyday transport feel special. Motobi’s small racers punched above their weight in Italian club events, and the brand became a stepping stone for young riders who wanted speed and style on a budget. Later reunification with Benelli preserved much of the know-how. Historically, Motobi represents the Italian genius for making small displacement engaging—bikes that feel lively at legal speeds and look like little sculptures even when parked.
