the balance amongst teams, giving MV Agusta a position of technical supremacy that it maintained for over a decade. Surtees (as Arturo Magni revealed later) did not like the six cylinder machine which was wider and heavier than the "four". The six-cylinder reappeared during the 1959 Nations Grand Prix practice sessions, but was not used in the race. The last evolution of the "500 6C" was prepared in the first months of 1960, but was then abandoned, given the futility of supporting its high development costs.
