Aspar retains Barbera for 2011

The 23-year-old Spaniard, who finished runner-up in the 250cc class last season, has finished in the top 10 in five of the 11 races so far this year - his and the Aspar team's first season in the top class.

"I am really pleased that we will continue to take this programme forward," said Barbera. "I was calm and confident that I would stay for another year, but once the contracts are signed and sealed that helps you to focus purely on racing.

"We are doing our job well. This is the most difficult project I have ever been involved with because MotoGP is the highest level, but I am satisfied we are working in the right direction.

"Now we head to some circuits where I went well last year so we're looking to end the season on a high. I am also sure that Valentino [Rossi]'s move to Ducati will bring a lot of experience and improve the bike."

Aspar team boss Jorge Martinez added: "Even though this is a learning year, Hector is doing a very good job considering the quality of the field. With the pace he has set he would have been in the top five two years ago, and it is hard to find another rider with the same level of performance and potential.

"Ducati has supported us ever since we began this project and they agree that Hector is an excellent rider with a long career ahead."
