An institution since 1949, the Road Racing World Championship Grand Prix is the series to watch for great motorcycle racing. And as far as the 2011 is concerned, you really only need to watch one rider: Casey Stoner. On Sunday, the Australian took first place in the Indianapolis GP, continuing his domination of this year’s season with his seventh race win, and third in a row.

After overtaking reigning world champion Jorge Lorenzo on lap 2, Stoner passed Repsol Honda teammate Dani Pedrosa on lap 7 of the 28 lap race. From there on, he was untouchable, and even set a new lap record for the course on his way to first place, driving the 2.261 miles in just 1:38.850- an average of 95 mph. He won the race by 4.828 seconds, followed by Pedrosa in second and American Ben Spies, the 2010 Rookie of the Year, in third place.  Check out the video highlights:

Stoner  won the world title in 2007, while riding for Ducati; he switched to Honda just this year. So far, it looks like a good choice. With this weekend’s win, Stoner now has a 44 point lead in the series over Spaniard Jorge Lorenzo, with just six races left.

High speed motorcycle racing can be a dangerous sport, even if you resist the temptation to pull stupid stunts. But that’s not enough to keep riders like Stoner off their bikes and out of the competition for glory. For Stoner, it looks like the risk is going to pay off in 2011.
