Jorge Lorenzo sealed his second MotoGP title at the Australian Grand Prix after his only challenger Dani Pedrosa crashed out of contention.
Pedrosa trailed fellow Spaniard Lorenzo by 23 points entering the race and had hoped to take the title battle to the final round, but his challenge ended when he lost control on the second lap at the Phillip Island circuit's hairpin turn four.
Lorenzo narrowly avoided the flailing Pedrosa and that was the last of his troubles as he settled into a fuss-free run to finish second behind local hero Casey Stoner.
Lorenzo pulled a wheelie and shook his fist in triumph as he crossed the line to seal the title.
"I'm really, really happy with this championship because only we know how difficult it is to fight with riders like Casey, like Dani. It is very hard," Lorenzo said.
"You must be very consistent, never make a mistake and always try to finish the races and be very focused - so today is a very special day."
Lorenzo - who also won the 2010 Championship - takes an unassailable 43-point lead in the title race, rendering the final round a victory parade in front of his home fans in Valencia.
