MV Agusta 350B  The MV Agusta 350B (Bicilindrica) was a series of motorcycles produced by the Italian manufacturer MV Agusta from 1970 to 1974. The motorcycle was first introduced at the Milan motorcycle show in 1969. The introduction of the "350" model was intended to bridge the production gap of MV Agusta in the medium-displacement sector and to take advantage of the prestige gained by the dominant GP racers. It was produced in "Sport", "Gran Turismo" and "Scrambler" versions. The series was replaced by the "MV Agusta 350 Ipotesi" in 1975. The four-stroke parallel twin OHV engine was derived from the existing 250 twin cylinder, the bore being increased by 10 mm to 63 mm to give 349 cc displacement. Featuring alloy barrels and heads, the cylinders were inclined forward by 20 degrees. Two 24 mm Dell'Orto carburettor fed fuel to the engine, which had a compression ratio of 9.2:1. Lubrication employed a wet sump. Power output was 27 bhp (20 kW) @ 7,600 rpm. A geared primary drive took power to the wet, multi-plate clutch. The unit construction gearbox had 5 speeds, and final drive was by chain. For the chassis, MV's usual single-beam frame in steel tube and sheet metal was used. Telescopic forks were used on the front, which because of the oil damping, were called "oleohydraulic forks" by MV. Rear suspension was by swinging arm and twin shock absorbers. Brakes were drums front and rear and spoked wheels were fitted. In 1972 the machines were fitted with electronic ignition and had cosmetic changes. These models were designated ""Elettronica"". The 350B Sport was the most popular model of the range with its sporty appearance and agile handling. A racing tank and humped seat were fitted with "clip-on" handlebars. The machine was finished in red with chrome fork legs, side panels, mudguards and headlight. It retailed at 510,000 lira in Italy. In 1972 the updated 350 B Sport Elettronica was introduced. As well as electronic ignition, it gained a new petrol tank and larger side panels. A sports fairing (Carenatura) kit was available as an extra. 2,083 Sport Elettronica machines were produced. A less sports styled version was also offered, the 350B GT, also known as the "350B Turismo".
