The MV Agusta 250 Bicilindrica was a 250 cc factory racing motorcycle manufactured by the Italian brand MV Agusta from 1957 to 1961. With this machine 11 GPs, 2 Driver Championships and 2 manufacturers World Championships were won.[1]

Development
The 250 Biclindrica ("two-cylinder") was developed in the new department in Cascina Costa, a neighbourhood in the south of
The fall of 1957 proved be a turning point for world road racing championships. All major Italian brands (Mondial, Moto Guzzi, Gilera and MV Agusta) decided to withdraw en bloc from the World Championships. The costs of racing were huge and disproportionate to the sales.[7] For Moto Guzzi and Gilera this was especially so, because their income was solely from motorcycle sales. Mondial was able to make some money with transport tricycles and for Agusta, motorcycle production was still more a hobby than a profession. Count Domenico Agusta reversed his decision and continued the racing activities. Without other factory competition for the 1958 season, MV Agusta elected to use the tried and tested single-cylinder. Tarquinio Provini won four of the six 250 cc races that season and became a world champion by a huge margin,[8] and MV won the Constructors Championship.[4]
The twin-cylinder machine was used by the works riders of Carlo Ubbiali and Tarquinio Provini for the 1959 season. Some privateers competed on the older single-cylinder machine.

The machine was extremely slim, and probably developed by Arturo Magni. The frame, a chrome molybdenum double cradle, exhibited all the characteristics of Magni's later frames. The tube diameter was 25 mm × 1.2 mm. The front fork was a telescopic fork, and the rear suspension was swingarm with hydraulic shock absorbers. 210 mm drum brakes were used front and rear, the front being [1][2]
