Cal Crutchlow set his fastest ever lap at Phillip Island as the British rider finished sixth on the combined time sheets on the opening day of the Australian MotoGP.

The Yamaha Tech 3 rider also dipped under Nicky Hayden's 2008 lap record with his time of 1m 29.667s on the newly resurfaced circuit as the top six riders surpassed the American's previous benchmark.

"Today was a good start to the weekend and I am satisfied to be in the top six. I'd like to be stronger on the brakes going into Turn 4, which can be important for overtaking in the race on Sunday," said Crutchlow.

"It was obvious that the new track surface is a big improvement and they have done a really good job in making it smooth with a lot of grip.

"A few of us were consistently under the lap record with a similar pace and hopefully tomorrow I can improve to be a bit higher up," added the 27-year-old.

"I was on the podium here last year and it was great to share the rostrum with Casey and Jorge. It will be difficult to repeat that on Sunday but I will be trying my maximum as always to get the best result possible for the Monster Yamaha Tech 3 squad."
