Moscow's Red Square has been overrun by motorbikes, as part of a freestyle Red Bull X-Fighters motocross competition taking place right next to the walls of the Kremlin.<br /><br />This was the first time an international event of this sort happened in Russia -- no wonder the spectacular event left onlookers open-mouthed: audacious riders threw somersaults as high as 10 meters up in the air, and somehow managed to stay on.<br /><br />Under the simple rules, each player gets just 90 seconds, after which he is given a certain number of points: the harder the trick, the better the result.<br /><br />18-year-old New Zealander Levi Sherwood won the race. Veteran and 2009 X-Fighters title holder Nate Adams finished second, while round one winner Andre Villa rounded out the top three.
