Jorge Lorenzo insists he isn't mentally troubled by his lack of victories this season.

The Movistar Yamaha rider won eight races last year, as he got to within four points of Marc Marquez and a third MotoGP crown.

However 2014 saw the Spaniard's worst ever start to a premier class season - persistent problems in adapting to the new Bridgestone tyres being compounded by a fall and jump start.

"I'm fine. Everyone has bad moments and bad years. For me it happened this year, especially the start of the season," said Lorenzo. "I have to accept it. Luckily for us we have come back and the results have improved again."

Lorenzo, who has finished runner-up at the last three rounds, added: "Obviously we want to win and we are working for it. At the moment we didn't get it. We just need the best conditions for victory to happen and we are going for it. Working really hard and I hope it will soon arrive."

On paper Lorenzo should have one of his best victory chances this weekend at Misano, where he has been victorious for the last three seasons.

"The past doesn't give you any advantage for this year, so we all start from zero. I don't why it works well for us, maybe the chicanes or the fast corners. Hopefully we can keep the tradition alive," he said of the Italian circuit.

Lorenzo is currently fourth in the world championship, but slowly reeling in team-mate Valentino Rossi. Marquez has won all but one race this season.
