Valentino Rossi is an Italian professional motorcycle road racer and multiple MotoGP World Champion. He is the only rider in the history of the World Championship to have won the World Championship in four different classes: 125cc , 250cc, 500cc and MotoGP
Rossi is one of the most successful motorcycle racers of all time, with nine Grand Prix World Championships to his name – seven of which are in the premier class , he is - now known as THE GOAT ( the greatest of all time) .
After graduating to the premier class in 2000, Rossi won the 500cc World Championship with Honda in 2001, the MotoGP World Championships (also with Honda) in 2002 and 2003 and continued his streak of back-to-back championships by winning the 2004 and 2005 titles after leaving Honda to join Yamaha. All of those titles were won in a dominant manner, being decided before the final round on all occasions. He lost the 2006 title with a crash in the final round at Valencia, ceding the title to his former Honda team mate Nicky Hayden. In 2007 Rossi and Yamaha were of no match to a dominant Casey Stoner on a Ducati, and Rossi ultimately finished a then career-low third overall.
Rossi regained the title in 2008 following several tight duels with title defendant Stoner and retained it in 2009. After a 2010 marred by a broken leg and no title challenge, Rossi left Yamaha to join Ducati for the 2011 season to replace Casey Stoner .
