German teenager Stefan Bradl heads to the Netherlands following his fourth Moto2 victory of the season at Silverstone.

The Viessmann Kiefer Racing rider has a superb record thus far in 2011, entering the Dutch TT with a 62 point lead, the greatest number of points that any rider has led a Grand Prix World Championship after just six races in any class of GP racing.

Bradl’s five successive poles have not been seen in the intermediate-class since Toni Elías in 2003.

Ioda Racing Project’s Simone Corsi is second in the championship, and is the only rider in Moto2 outside of Bradl to have scored points at all of the six races this year.

Though only finishing 12th at the Dutch TT last year, he crossed the line seven places ahead of Bradl in 19th.

Moving into third place in the championship hunt, nine points behind Corsi, is Yuki Takahashi, who finished 10th last year in the Moto2 race at Assen from 13th place on the grid. The Japanese had his best result at the Dutch TT with a 6th place in the 250cc race in 2006.

Fourth with 49 points is Speed Master’s Andrea Iannone, who, although he started the season strong, has finished outside the points twice in the last four races.

The Italian will be looking to turn his season around at the Dutch TT, where he positively dominated in last year’s Moto2 race, qualifying on pole and leading every lap of the race.

Iannone is matched in championship points by Mapfre Aspar rider Julián Simón, who is recovering from surgery on a fractured tibia and fibula he sustained at the Catalunya GP. Simón will have a new replacement rider in the form of Elena Rosell for the upcoming Assen GP.

The 25-year-old Rosell currently races in the Stock Extreme series of the CEV Buckler (Spanish National Championship) and will be the first woman to compete in the intermediate class since Katja Poensgen took part in the 250cc championship eight years ago.

Thomas Luthi is sitting sixth in the championship points and proved to be a strong rider here when he finished third in the 2010 Moto2 race while suffering from shoulder injuries received in a motocross training accident.

One point behind the Swiss rider is Bradley Smith, whose incredible second place after starting from 28th on the grid at Silverstone moved him into the top Rookie position in the class, two points ahead of Marc Márquez.

Catalan rider Márquez won the 125cc race at the Dutch TT last year from a pole position start.

The Moto2 class will feature two wildcards for the Assen race, Dutch rider Michael van der Mark (EAB Racing) and South African rider Steven Odendaal of MS Racing.
