Dani Pedrosa, Honda, 4th, 206 points – Score: 8
If you wanted the very definition of a roller coaster career, look no further than Dani Pedrosa. Three world championships in the junior classes, and one of the most successful riders in the premier class.
He has never won a championship, but he has come within a whisker in 2012, winning more races than the eventual champion Jorge Lorenzo. Injury has dogged him, breaking most of the bones in his body, and fracturing his collarbone so often there is hardly a piece left intact.
His collarbone nearly ended his MotoGP career once, the plate fitted after his practice crash in Motegi in 2010 causing Thoracic Outlet Syndrome, causing numbness and weakness in his left arm, making it almost impossible to last a race.
He suffered through 2011, until the removal of the plate on his collarbone fixed the problem. He was back with a vengeance in 2012, winning seven races and getting close to beating Jorge Lorenzo. That experience stood him in good stead in 2015.
