Suzi Perry presents live coverage of the third round of the MotoGP from Istanbul in Turkey. Valentino Rossi's win in Spain last time out took him top of the standings, as he seeks to regain the title he lost so dramatically to Nicky Hayden last season. Likely challengers are Dani Pedrosa, who was second in Jerez, and Casey Stoner, who won the opening race in Qatar. Charlie Cox and Steve Parrish are the commentators.
