In 1959 MV Agusta started with the design of a 125 cc desmo double knocker with a very similar Mondial lay-out.
Designed by Ruggero Mazza* who came from the race department of Ducati.
Tarquinio Provini used the Desmo in the first race of the Italian Championship, but for unknown reasons it was abandonned for the rest of the season.

The project was stopped in 1960, because MV Agusta, like Ducati, stopped racing in this discipline for economical reasons and because the Japanese entered the 125 championship.
