41 seconds ahead second placed Masetti. Hermann Paul Müller finished third on the NSU Sportmax. Although only third, it was clear that he was competition for the world title. However, the rankings of Taveri and Masetti were very important for the constructors' title. In the Ulster Grand Prix, Müller was only sixth, but MV Agusta did not do well, Masetti was in third and Lomas fourth. In the final race, the GP des Nations at Monza, Carlo Ubbiali, who was already 125 cc world champion, won the 250cc class for MV Agusta, with Lomas fifth and Masetti sixth. The world title went to "HP" Müller, Bill Lomas came in second, Luigi Taveri fourth, Umberto Masetti fifth and Carlo Ubbiali seventh. MV Agusta won the constructor's title. In 1956 the MV Agusta 220 Bialbero was succeeded by a fully-fledged 250cc machine, the MV Agusta 250 Monocilindrica Bialbero. Technical data The 203 Bialbero had an air-cooled, single-cylinder, four-stroke engine with double overhead camshafts (DOHC). The camshafts were driven by a gear train. The valves were at an angle of 90° to each other and were closed by hairpin valve springs. The bore and stroke were 68 mm × 56 mm, giving an engine displacement of 203.4 cc. After the Isle of Man TT, the bore was increased to 71 mm, giving a capacity of 220 cc. A Wet multi-plate was driven by gears from the crankshaft. The machine had five gears and the rear wheel was driven by a chain. The MV Agusta had a double cradle frame that was constructed from chrome molybdenum tubes with a diameter of 25 mm × 1.2 mm. The front fork was a telescopic fork, and the rear suspension was swingarm with hydraulic shock absorbers.
