Champions
The Riders' World Championship is awarded to the most successful rider over a season, as determined by a points system based on Grand Prix results.
Giacomo Agostini is the most successful champion in Grand Prix history, with 15 titles to his name (8 in the 500cc class and 7 in the 350cc class). The most dominant rider of all time was Mick Doohan, winning 12 out of 15 500cc races in the 1997 Grand Prix motorcycle racing season (or 80% of the year's races), in the same year Rossi could only manage 11 out of 15 125cc victories. Valentino Rossi is the most successful contemporary rider, having won 9 titles including 6 Moto GP titles, and 1 each at 500cc, 250cc and 125cc levels. The current (2010) champion is Jorge Lorenzo.
