Motorcycle racing is a broad field that encompasses all racing aspects of motorcycling.
The FIM is the international sanctioning body for motorcycle racing and most nations have their own governing bodies. Other breakaway/independent bodies exist on both a national and an international level.
Motorcycles vary greatly in design for each discipline. Broadly speaking, motorcycle racing can be divided into two categories: tarmac-based road disciplines and off road. Within each of these disciplines, there are usually sub-groups.
Agostini was born in Lovere, in Lombardy, the son of a wealthy, Italian industrialist. His father originally didn't approve of his son's motorcycle racing career. He did everything he could to persuade his son not to race. Agostini would have to steal away to compete, first in hill climb events and then in road racing.
Eventually his father came to terms with his racing and he won the 1963 Italian 175cc championship aboard a Morini. He got his break when Morini factory rider, Tarquinio Provini left the team to ride for Benelli. Count Alfonso Morini hired the young Agostini to ride for him. In 1964, Agostini would win the Italian 350cc title and proved his ability by finishing fourth in the Italian Grand Prix at Monza.
