Rossi quits again

Rossi says no to F1, again

MotoGP champion Valentino Rossi has said no to F1, again saying this time it's for keeps and he will never compete in the sport.

Rossi tested for Ferrari again before Christmas but both sides said there was no real intent behind it, in terms of geting him to switch from two wheels to four.

"I had my chance for F1 and I decided to stay with bikes," Rossi said. "I've made my choice and I don't think there's any other possibility now."

Rossi's contract with Yamaha in MotoGP runs until the end of 2010.
