MotoGP front runners have called for Indianapolis to be re-surfaced before they return to the track in 2014 in the light of a new deal being struck for the American track to host the race again in next season.

The future of the meeting was in subject to much speculation but bosses have signed an extension into next year which puts the MotoGP race at Laguna Seca in doubt due to concerns over safety and the fact the paddock isn't large enough to accomodate Moto2 and Moto3.

The circuit's surface came in for criticism from most riders, with Cal Crutchlow and Valentino Rossi in particular saying most of it needs new asphalt as the infield is very slippery.

"There is a quite a lot I would like to see change. We want turn four changed because to go around it, you might as well slip the clutch. After turn five to the end of the lap, the surface is so slick you can't really pass because you can't run off line," said Crutchlow.

"If you do you're going in the grass really. First and foremost we want the surface changed and then see if we can change a little bit the first and last sectors. I'd like to run around the banking into turn one, but no-one else wants to do it! I don't know what's the matter with them. It's a great idea.

"If we open up turns two and three so it's not so tight and four can be more of a sweeping corner because now it's first gear at 3000rpm for all of us."

Rossi added: "Indy want to continue to do the Grand Prix and they are ready to do a lot of work for improve. The main problem is the asphalt they use for the infield is very bad - the quality is not fantastic so maybe this is the base for improve the racetrack."
