#2 Casey Stoner
Casey Stoner, now a retired Australian professional motorcycle racer, is a two-time MotoGP world champion. He was just four years old when he competed in his first race. When he was young, he raced in five different categories in all seven rounds of each capacity.
It was a weekend which consisted of 35 races out which he won 32 races. His parents took him to England to let him try racing in the premier class as he was not legally authorized to race in Australia till the age of 16.
Stoner immediately made an impact and attracted the sponsors in 2000 when he went on to win the English 125cc Aprilia championship. It was in 2006 when he fulfilled his ambition of racing in MotoGP.
He had a great start to his MotoGP career as he finished at the pole position in just his second race. 2007 was the best year for Casey as he joined Ducati with whom he won his first MotoGP championship.
In 2008, he finished at the pole position for seven times in a row but due to several crashes, he finished runners up just behind Valentino Rossi. When he joined Honda in 2011, he immediately adapted to the changes and won three out of five races in that season.
He won nine races in the season and ended up being 65 points ahead of Jorge Lorenzo. This was his second World Championship. He is also known for his intense battles with Valentino Rossi during his career.
Stoner shocked the world when he announced his retirement at the end of the 2012 season at the age of just 27 citing personal reasons and the direction in which the championship was going also helped him make this decision.
