VALENTINO Rossi had another weekend to forget at Laguna Seca.
Rossi crashed out of eighth place, losing the front on the approach to the Corkscrew with three laps to go.
Speaking to the press, Rossi said: "I wasn't fighting for a podium place, but a crash like that at the end of the race is still disappointing. I lost the front when I was approaching the Corkscrew, when the bike was vertical, just as I touched the brake, a bit like what happened at Silverstone.
"We have a real problem. Again, today, we had a hard time getting the front tyre to work - it was like brand new after 30 laps.
"It's a pity because we've had this problem for a long time and we are not able to fix it."
Rossi's team-mate Nicky Hayden has just extended his contract with Ducati, quashing rumours that Cal Crutchlow would take his place. Valentino Rossi is expected to announce his future plans before the Indianapolis GP in a couple of weeks.
