Valentino Rossi stamped his authority on the opening practice of the weekend with the fastest time of Friday, lapping the Barcelona track in 1'43.038. The Italian has never finished outside the top three in a premier class race at Barcelona and he signaled his aspirations for victory by starting the weekend on the front foot.
Behind Rossi on the timesheet was his factory Yamaha colleague Jorge Lorenzo who was 0.302 off the Rossi's pace on a far better Friday than last year at his home track - where he crashed in practice and missed the race due to concussion. Third on the timesheet was Mugello race-winner and 2007 Barcelona victor Casey Stoner who went round just over half a second slower than Rossi on his Ducati Desmosedici, despite a small crash near the end of the session.
Fourth on the timesheet, just as he has been in the last two MotoGP races, Andrea Dovizioso put in a similar time to Stoner. Dovizioso's injured Repsol Honda team-mate Dani Pedrosa was down in 14th place as he tested the condition of his injured hip. At one of his favourite tracks Randy de Puniet was fifth fastest, whilst a big improvement by Ducati's Nicky Hayden saw him finish sixth quickest in one of his best sessions of the season so far - around a second off the pace.
Veteran riders Loris Capirossi and Colin Edwards were seventh and eighth respectively. Yuki Takahashi was number nine on the timesheet, trying to push hard after seeing new MotoGP recruit Gabor Talmacsi join the Scot Racing Team on Friday. Talmacsi was unsurprisingly the slowest participant in his first 800cc session, four seconds behind Rossi.
