Marc Marquez took full responsibility for crashing out of the lead of Sunday's Australian MotoGP.
The newly crowned triple world champion was holding a comfortable advantage when he lost the front under braking for the Honda hairpin, on lap 10 of 24.
Marquez had suffered the same fate while leading at Phillip Island in 2014, although on that occasion he was one of several riders caught out by a cold front tyre.
Although he chose the hardest front tyre option on Sunday, the Spaniard declared his accident occurred purely because he took too big a risk in trying to make the corner after missing his braking point.
“First of all I want to say sorry to my team because I made a mistake today," Marquez began. "We were doing everything perfectly, and we were just missing capping it with a result on Sunday. If I had been fighting for the title it would've been an entirely different race, as I wouldn't have risked so much.
"Today I started strong because I knew I had to make a difference at the beginning. I was maintaining the distance, but at one of the hard braking points I braked too late and instead of taking a wider line, which is what I had been doing throughout the year, I tried to keep going. In such cases the limit is a fine one.
"We remain happy of course because we had already won the title but of course we wanted to win more races.
"It was completely my mistake; during the whole season I've been very careful on the braking points and this time I risked more so this crash has nothing to do with the Michelin tyres. Now we have another race next week, and we'll just think about that. Congratulations to Cal for his great victory”.
Fellow Honda rider Crutchlow went on to win from Valentino Rossi (Yamaha) and Maverick Vinales (Suzuki).
