MotoGP has agreed an unusually short one-year extension to its present contract with Indianapolis Motor Speedway, which expires after this weekend's event.

The first Indianapolis MotoGP round was held in 2008, marking the start of a three-year contract.

Dorna Sports CEO Carmelo Ezpeleta suggested that the short extension was due to the present MSMA (MotoGP manufacturers) and IRTA (Teams) contracts with Dorna and FIM expiring at the end of 2011.

The MSMA and IRTA contracts haven't been seen as a significant factor in agreements with other circuits, some of which have deals to host MotoGP until 2016, but it's a sign that Indianapolis has doubts over what will become of the sport under the new 1000cc rules.

"The extension of the agreement for a further year allows all parties involved to continue providing a superb weekend of racing at Indianapolis next season," said Ezpeleta. "It permits all possibilities to be explored at the end of 2011 when the current contractual agreement with the MSMA and IRTA is reviewed, as MotoGP continues to develop into a new era in the sport in 2012."

"We're thrilled to welcome back the stars and machines of MotoGP in 2011," added Jeff Belskus, Indianapolis Motor Speedway Corporation President and CEO. "This is a unique weekend that our fans enjoy, bringing the international flavour and great action of MotoGP to the Speedway. It has been a successful race for the last three years, including a great partnership with Red Bull, and we are working hard to continue to develop the event."

Next year's Indy round is scheduled for 26-28 August.
