If points MotoGP leader Jorge Lorenzo finishes in the top two at this event, he will become just the third rider in the 62-year history of Grand Prix motorcycle racing to finish either first or second in the first 10 races of a season.
Multi-time World Champions Giacomo Agostini and Mick Doohan are the only riders to achieve that feat.
Lorenzo has three career victories at Brno but none in MotoGP. He won in 250cc in 2006 and 2007 and in 125cc in 2004.
Seven-time MotoGP World Champion Valentino Rossi has earned five victories in his 10 career starts at Brno in the premier class. He also earned his first Grand Prix victory at this track, in 125cc in 1996.
Brno is one of the few circuits on the MotoGP schedule at which American rookie sensation Ben Spies has racing experience. He won a Superbike World Championship race in 2009 at the track en route to the series championship.
The 2007 MotoGP World Champion Casey Stoner is winless in his last 10 starts, his longest drought since joining Ducati in 2007.
Rossi plans to announce his 2011 racing destination August 15 after this race. He is widely expected to move from the Fiat Yamaha Team to the iconic Italian manufacturer Ducati Team.
If a Spanish rider wins this event, it will be the nation’s 50th victory in the premier class. Spain would join Italy, the United States, Australia and Great Britain in that exclusive club.
Just two riders have scored points in all nine MotoGP races this season: Lorenzo and Andrea Dovizioso
LCR Honda MotoGP rider Randy De Puniet returned to race at this event just 23 days after undergoing surgery to repair a broken leg suffered in the Grand Prix of Germany on July 19.
125cc points leader Marc Marquez, 17, became the youngest rider to win five consecutive races in the World Championship with his victory July 18 at Germany. Marquez is the first 125cc rider to win five consecutive races since Rossi won six in a row in 1997.
Spanish riders have won 18 consecutive 125cc races in the World Championship, dating back to last season.
