MotoGP ace Stoner aware of 'life-changing' risks
Australian ace aims to crown his final year, despite still limping from knee injury

MotoGP champion Casey Stoner says he has recovered only 50 per cent from injury but is ready to take "life-changing" risks in his comeback to crown his final year in Grand Prix racing.
The Australian is set to race at the Grand Prix of Japan tomorrow, having missed the last three events after injuring his right knee in a crash during qualifying at the Indianapolis Grand Prix in August.
The Honda rider's absence means it is now impossible for him to retain his crown, with the 2012 championship currently led by Yamaha ace Jorge Lorenzo, on 290 points, and Honda's Dani Pedrosa, in second place on 257.
"Fifty per cent, maybe," said Stoner, still seen limping, about the progress of his recovery.
"I expected my body to be up around 80 per cent, trying to be 70 or 80. But it's not even close to that right now. So I'm a little bit disappointed that we didn't make a little more progress with the injury."
Stoner underwent surgery on August 30 after suffering torn ligaments and fractures to his ankle, tibia and fibula at Indianapolis, although he still lined up for the race and finished fourth.
