Biaggi and Rossi shake on it.

Yesterday Max Biaggi met with title-rival Valentino Rossi to shake hands over their post-race 'disagreement' at Catalunya.

The riders have been threatened with sanctions if they should contravene GP racing's sporting code again, and they've both admitted that the warning could affect their riding.

"I respect the rules and I respect what they've said to us," said Biaggi. "I'm thinking about it all the time, what I should do, what I shouldn't do."

Rossi added: "It's having a big effect, if Max or I do something wrong again, we'll have to stay home for one race."
