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. Technical details 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 @ 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
