Jorge Lorenzo won't go all out to secure his second MotoGP title at this weekend's penultimate Australian round.

The Yamaha star holds a 23-point lead over Honda's Dani Pedrosa, with 50 points remaining. That means if Lorenzo can beat Pedrosa by three points on Sunday, he will be champion for a second time.

However Pedrosa has won all five of the races he has finished since Laguna Seca in July - Lorenzo winning the other, at Misano, when Pedrosa was taken out on the opening lap.

Lorenzo would naturally like to secure the title on Sunday, but seemed relaxed at the prospect of a final round showdown.

"Only two races to the end. More than ever we must really concentrate and focus. Not make any mistakes," said Lorenzo.

"It would be great [to win the title on Sunday] and we have possibilities, but we will not go crazy to make it here. The most important thing is to make it. We are going to try here but not ignore the consequences."

Lorenzo was forced to withdraw from last year's race, ending his slim hopes of catching championship leader Casey Stoner, after suffering a gruesome finger injury in morning warm-up.

"Last year was a really bad weekend with my injury, but it could have happened anywhere so I have no bad feelings for this track," he said.

"Phillip Island is very special. Very different from others tracks. Really narrow and fast, the landscape is wonderful. It's nice to ride and compete here, especially when there is no wind and rain."

Lorenzo and Pedrosa head into the penultimate round having both won six races and suffered one DNF.
