Dani Pedrosa apologised to his team and supporters after his MotoGP championship defeat, but said he was still proud of his title campaign.
Jorge Lorenzo clinched the 2012 championship at Phillip Island on Sunday with second place behind Casey Stoner, as Pedrosa crashed out of the lead on lap two.
"Maybe it was too early to push," said Pedrosa. "I went a little bit wider on that corner. I lost the front."
Pedrosa had a muted start to the season. After six races he trailed Lorenzo by 39 points and was only third in the standings.
Lorenzo's Assen retirement revitalised Honda's title chase, and Pedrosa took his first wins of the season in Germany and the Czech Republic, before being taken out at Misano.
That incident put Lorenzo 38 points clear and seemed to signal the end of the title fight, only for Pedrosa to go on a three-race winning streak and get the gap down to 23 points before his Australian Grand Prix disaster.
"I'm proud of how I've competed," said Pedrosa.
"I feel bad for those who support me, my family and my fans.
"I tried to give it everything all year."
