Defending champion Jorge Lorenzo said he was back to full health going into this weekend’s San Marino MotoGP, as the Spaniard prepares himself for another run at the title.

Lorenzo, who suffered a broken collarbone at Assen in June, twice underwent surgery following his initial heavy crash in the Netherlands and a subsequent accident in Germany two weeks later.

However, the two-time world champion said his injuries had finally healed and he was back in proper physical shape.

“I feel strong again like I was at Montmelo and Mugello before the crash,” said Lorenzo, referring to wins in Italy and Catalonia before his fall in Holland.

“Misano is a track I enjoy a lot and also the Yamaha is comfortable there. My next goal is to fight for the victory once more and think race by race, improving our pace step by step,” added the Spaniard, who has won the past two races at Misano.

Lorenzo halted leader Marc Marquez’s four-race winning streak when he triumphed at Silverstone a fortnight ago, but he is still 39 points adrift of his rookie compatriot in the riders’ standings with six races remaining.

Having seen title rivals Lorenzo and Dani Pedrosa both struck down by injuries, Marquez dislocated his shoulder at Silverstone but the 20-year-old was confident it would not hamper him at Misano.

“I’m already feeling much better since my accident in Silverstone, so hopefully I’ll be almost 100 per cent by this weekend,” said Marquez, who finished second in Britain despite the setback.

“I will arrive in Italy for the race weekend a little later than usual as I will use the time to have more physiotherapy on my shoulder,” added Marquez, who has been on the podium at every race bar June’s Italian MotoGP, where he crashed while running second.

Pedrosa, second overall and trailing Honda teammate Marquez by 30 points, is eager to cut the gap after finishing a frustrating third at the British MotoGP.

Seven-time champion Valentino Rossi’s return to his home circuit will be greeted with the usual fanfare.

“Misano is next and it is my home Grand Prix and an important weekend. I like the track; I always go fast there, especially with the Yamaha.”

A winner at Misano in 2008 and 2009, Rossi is fourth in this year’s standings, 38 points in arrears of Lorenzo.
