Laureus World Sports Academy Member Giacomo Agostini Over the course of a remarkable career of 17 years, the peerless Agostini won 15 World Championship titles, 10 Isle of Man TT crowns, an astonishing 122 Grand Prix. He became motor cycling’s first genuine world superstar and, whether riding a 350cc or 500cc, he was nearly always the man to beat whenever he took up his position on the starting grid.
