Seventy years on there are 19 Grands Prix visiting 15 countries in five continents with riders from 19 countries competing for the ultimate prize in the three classes Moto3™, Moto2™ and MotoGP™. In 1949 there were six Grands Prix all in Europe and, apart from Monza in Italy, all on circuits that were public roads for the rest of the year. The six circuits picked to stage these pioneering races were the Isle of Man, Berne in Switzerland, Assen in Holland, Spa -Francorchamps in Belgium, Clady in Northern Ireland and Monza in Italy. There were four solo classes 125, 250, 350 and 500cc and of course the magnificent sidecars. The 500cc class was staged at every round, but the 350cc at five, the 250cc at four and the 125s at just three.
