Having tied Jorge Lorenzo for the MotoGP title lead at Assen, reigning champion Casey Stoner will be aiming to break free of the Spaniard this weekend in Germany.

While Lorenzo was taken down by Alvaro Bautista in Holland, Stoner swept to his first victory since Estoril to erase the Yamaha rider's 25 point advantage.

With the points now equal after seven rounds, Lorenzo is ahead only on the race wins tie-break (four wins to three for Stoner).

Although the post-race talk naturally focused on Lorenzo's troubles, Stoner had looked in most difficulty heading into the race, following a big practice accident and chatter problems with his Repsol Honda.

"I hope we can go to Sachsenring and get another good result especially after our tough, but rewarding weekend in Assen," said Stoner.

"We were quite competitive there last year, but in the long corners we are struggling a little more with our bike at the moment so we're going to need to work hard on Friday and Saturday, try to find more grip from the edge of the tyre and also see if we can reduce the front chatter."

The twisty layout could also put Stoner's injured knee to the test.

"Assen was the first time I haven't got up and walked straight off after a crash. It really hurt," he said, adding; "I'm not liking the fact that that first section [at Sachsenring] is all long right handers, that's going to hurt my leg, but in general we've had good results."

Stoner won at Sachsenring for Ducati in 2008 and has been on the podium for the past two years.

"It's a very interesting track, maybe not one of the greatest on the circuit but has one of the best corners coming down the hill which is a little scary with spending so much time on the left before switching to the right side of the tyre," said the Australian.

"It's a good atmosphere there though with all the spectators so close to the track, it feels like a Coliseum! There's always an interesting race there as we saw last year so we'll see what this weekend has in store".

Team-mate Dani Pedrosa, 19 points from the title lead, has won at Sachsenring for the past two years.
