The Spaniard Jorge Lorenzo won his seventh race of the season at the Czech Grand Prix overnight to extend his Moto GP championship lead to 77 points.
The 23-year-old Yamaha rider started third on the grid but quickly jumped into the lead on the first lap, where he stayed for the rest of the race on the 5.4 kilometre Brno circuit.
He finished more than five seconds ahead of compatriot and championship rival Dani Pedrosa, who began on pole.
Australian Casey Stoner, who is third in the standings, finished third on his Ducati, beating out Ben Spies into fourth in the American's first front row start.
Italian world champion Valentino Rossi finished fifth, where he started the race.
Lorenzo becomes only the third rider in 62 years of GP to finish in the top two in the first 10 races of a season.
