Niccolo Canepa's perfect finishing record as a MotoGP rider came to an end at round twelve in Indianapolis on Sunday, when his Pramac Ducati 'switched off' six laps from the finish.

The Italian rookie was holding 13th place, just behind Toni Elias (Gresini Honda) and Chris Vermeulen (Rizla Suzuki) when the problem occurred - and felt he had a shot at a top ten finish.

"I was fast. I wanted to ride in the top ten, and it was possible. I could have fought with Elias and Vermeulen, but a problem with the electronic system suddenly switched off my bike," he said.

"I am very sorry because I needed a good result and I now hope that I will have the possibility to achieve it in Misano," added the #88.

Following Canepa's exit, and Marco Melandri's crash, new team-mate Aleix Espargaro finished 13th on his MotoGP debut.
