Organizers of the Laguna Seca round of MotoGP have signed a new deal that will see MotoGP stay on at the Californian circuit until 2014.

"This is tremendous news on so many levels," said Gill Campbell, CEO of Laguna Seca.

"MotoGP is the world's premier motorcycle racing series, and we now have the pleasure of hosting it for the next six years."

The circuit, which is own by Yamaha USA, has had important improvements done over the past four years.
