10 world titles were achieved by riders John Surtees, Gary Hocking and Giacomo Agostini on these machines.

Designer Piero Remor initially provided that machine with experimental and often useless technology, but rider Leslie Graham made some improvements.

[10] At the end of 1957, the Italian brands Gilera, FB Mondial, Moto Guzzi and MV Agusta announced that they would stop road racing.

With the loss of the biggest competitors (the British brands had stopped earlier), the fortunes for MV Agusta turned.

[13] The 1960 season was exciting due to the battle between the two teammates from MV Agusta, John Surtees and Gary Hocking.

[21] Hailwood then won in the GDR and in Finland, but by then the world title was already decided in favour of Jim Redman and Honda.

MV had two top drivers: Mike Hailwood and Giacomo Agostini, who took points off each other, while Honda put everything on Jim Redman.

In the first 350 cc race of 1965 at the Nürburgring, Agostini won ahead of his teammate Hailwood and Gustav Havel on a Jawa, while Redman (Honda) crashed in the rain and broke his collarbone.

[25] During the Junior TT, Redman was out for his third win in a row, but Hailwood led by 20 seconds after the opening round with the new MV three-cylinder.

The MV Agusta of Hailwood stopped at Sarah's Cottage on the fourth lap, giving Redman the win.

Phil Read was second with the 250 cc Yamaha and Agostini took third place after Derek Woodman with the MZ had dropped out on the final lap.

Just like in the 125cc class, two drivers were on 32 points before the start of the 350 cc race in Suzuka: Jim Redman and Giacomo Agostini.

An exciting race for the world title was expected, but Agostini's engine started running poorly due to a broken Contact breaker spring.

[28] At the season open race in the 350 cc class, the German Grand Prix at Hockenheimring, Giacomo Agostini retired and Mike Hailwood won on the Honda RC 173.

[31] Hailwood won the German 350 cc Grand Prix with Giacomo Agostini almost a minute behind on his MV Agusta.

[33] In Ulster, Hailwood concentrated on the classes in which he was not yet a world champion, the 250 and 500 cc, and Ralph Bryans rode his six-cylinder Honda.

Now that the title had been decided in favour of Honda, the 350 cc race at Monza was more for the Italian honour for Agostini and Renzo Pasolini (Benelli).

[28] Renzo Pasolini on the Benelli was the nearest competitor, but Agostini won all seven Grands Prix, sometimes lapping the whole field.

[36] Agostini won the first eight races, but because Count Agusta did not agree with the move of the GP des Nations to Imola, he did not ride there.

[40] The 1971 season started sadly for MV Agusta, when Angelo Bergamonti was killed in a crash during the spring race in Riccione.

To offset the weight of the complex engine compared to the simpler Yamaha twins, the cycle parts were made as light as possible.

In the Junior TT, where Saarinen refused to ride due to the risks, Agostini led from start to finish, while his team-mate Phil Read dropped out on the second lap with shift problems.

Agostini dropped out in the GDR, but Phil Read now also had a four-cylinder MV Agusta at his disposal and won,[37] setting a new lap record.

Agostini's sixth win in Finland gave him the 1972 world title, with Saarinen in second place.

The Harley-Davidson team had skipped the German GP to work on the new water-cooled machines and that paid off: Pasolini was less than a second slower than Agostini in practice.

[51] The 350 cc race in Assen led to a great fight between Agostini, Read and Länsivuori, until the latter had problems with his gearbox and had to quit.

[56] Giacomo Agostini left for the Yamaha team at the end of 1973 and Phil Read became No 1 at MV Agusta.

In France a stone hit the distributor cap, in Austria the clutch slipped, in Italy, Yugoslavia, Czechoslovakia and Germany, Ago stopped for unknown reasons and in Finland the ignition broke down.

The six-cylinder in- line engine was a logical development because MV Agusta built a 500 cc version in response to the Moto Guzzi Otto Cilindri.

This machine had a trellis frame that consisted of triangular constructions of thin tubes, and where the engine was a structural part.
