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. History MV Agusta had started participating in road racing with motorcycles in the late 1940s and initially concentrated on the 125 and 500 cc classes. Piero Remor built the 125 "Bialbero" ("twin-cam") for the 125 cc class. The machine was subsequently bored to 175 cc because that class was still very popular in Italy and almost all major brands built production racers for it. The 175 cc machine was further bored to slightly above 200cc, so that in 1955 it was possible to compete in the 250cc class with the MV Agusta 203 Bialbero. After one race the capacity was further increased to 220cc. With that machine, Bill Lomas completed the 1955 season, finishing in third place in the World Championship. MV Agusta also won the constructor's title. In 1956, a new single-cylinder was developed from the 220 with a fully-fledged 250 cc engine: the MV Agusta 250 Monocilindrica Bialbero. This machine was good for the world title of 1956, but in 1957 they had to bow their heads to FB Mondial. Tarquinio Provini became world champion on the Mondial 250 Bialbero. Development The 250 Biclindrica ("two-cylinder") was developed in the new department in Cascina Costa, a neighbourhood in the south of Samarate in response to the dominance of the Mondial 250 Bialbero. This was the first racer that MV Agusta had developed entirely by itself. The single-cylinder still had all the characteristics of the pre-war Benelli 250 and the four-cylinder models were based on the Gilera 500 4C. The machine was first used at the 1957 Belgian Grand Prix at Spa-Francorchamps by John Hartle, who won the race. After Roberto Colombo died during practice at Spa, MV Agusta withdrew from the 250 cc class for the rest of the season, so the machine was not used again that year. 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. For Moto Guzzi and Gilera this was especially so, because their income was solely from motorcycle sales.
