The top riders get a decent salary, typically it can range from 350K well into the millions a year. If they win at the races, from sponsors, prize money and contingency money they can make up to 50-100K a race on top of that.
If they win a championship they can earn an easy million dollars bonus.
2010 Ryan Dungey made over around 6-7 million from Suzuki and Sponsors for winning the supercross and Motocross championship.
A year ago a privater racing a Kawasaki KX450 winning a outdoor national (1-1) finish would had made 54K just from the winnings not including the sponsor money.
Top riders that race for a Factory team, i.e. Yamaha - Suzuki.... etc. i.e. James Stewart, Chad Reed .....earn in excess of $ 3 million per year. Others may make just enough to survive. That is why racers always thank their sponsors on camera.
