MV Agusta 350 Six-cylinder

.  

In the summer of 1957 Nello Pagani, the official MV Agusta racer, went to Monza to test a new racing model for the 500 class, along with John Surtees' four-cylinder racer.
The new MV Agusta 500 followed the same general lines that the company had laid down with its first Grand Prix single-cylinder racer.

The engine was a four-stroke model with two-camshaft overhead distribution that worked two sharply inclined valves for each cylinder. The novelty was in the splitting of the displacement among six cylinders. Indeed, Moto Guzzi in that same period was developing an eight-cylinder 500. The MV 500 that Pagani was to test at Monza had six cylinders in line that were arranged transversely to the direction of the vehicle. Each cylinder had a displacement of only 83 cc. (46.2 mm. X 49.5 mm.). The motorcycle's maximum power was about 80 h.p. at 12,000 r.p.m.

Nello Pagani tested the motorcycle for a long time and John Hartle raced it at Monza. But after Guzzi and Gilera withdrew from racing, MV Agusta went back to its old four-cylinder model. The MV six-cylinder was then built in a 350-cc. version and was raced in 1971 by Angelo Bergamonti at the Modena trials.
