In the early 1960s, MV Agusta decided to return to offroad sport (at the end of the 1950s, MV racers were successful in enduro races, including in the famous Six Days race). A new 125 Regolarita was created by order of Fiamme Oro team. The model was equipped with a 125 cc engine boosted up to 12.5 hp and a five-speed gearbox. Traditionally light MV frame was reinforced with a lower subframe, becoming closed. 19-inch wheels got offroad tyres. This motorcycle became successful, so tens such motorcycles were also sold amateur racers. Moreover, a five-speed gearbox has become standard for 125 cc and 150 cc road motorcycles since 1966, the factory line-up was supplemented by the Scrambler version.
