After leading the Yamaha charge during the first half of the 2014 MotoGP season - including battling for victory at Qatar, Jerez, Le Mans, Mugello and Catalunya - Valentino Rossi now heads for 'tracks that are difficult for me'.

Those circuits include Indianapolis, where the action restarts this weekend with Rossi third in the standings, 84 points behind Honda's unbeaten reigning champion Marc Marquez but only seven adrift of Dani Pedrosa.

Rossi won the inaugural storm-shortened 2008 Indianapolis round, but has not returned to the podium since.

"This break was very important, I was able to rest and recharge to start this second part of the season in the best way. The upcoming races will not be easy because we will now arrive at tracks that are difficult for me," said the Italian.

"Indianapolis is not my favourite track, but they changed the layout and the asphalt a little bit, so we have to see. We hope to be competitive there and to be competitive for all the second part of the season."

Turns 3, 4, 7, 15 and 16 have been slightly reconfigured for this weekend, with the entire infield section resurfaced.

Rossi's team-mate Jorge Lorenzo, currently fifth in the championship, has five MotoGP podium finishes at Indianapolis.

The Doctor now holds the all time record for Yamaha premier-class starts, having made his 144th last time in Germany, taking the record from the late Norick Abe, whose last
MotoGP start at Valencia 2004 was his 143rd appearance riding Yamahas.
