Having been fastest during testing at Sepang for a perfect third day in 2010, MotoGP champion Valentino Rossi admitted he's eager to see how the new M1 performs on a different circuit.
The Italian completed 47 laps in withering 37-degree heat during Thursday's opening day of the second Sepang test. Rossi's best lap time was a 2min 1.068sec, just a fraction off his best time at the last test and enough to keep him 0.151 ahead of nearest rival Casey Stoner (Ducati).
There will now be one more day of testing at Sepang on Friday, before the third and final pre-season test is held at Qatar, also venue for the opening race of the year.
"We started well today and we're already very fast, so we're quite happy about this,” said Rossi. “We've confirmed that the work we did at the last test was good and it's clear we're in good shape at this track.
“We worked on two or three different settings and today we've more or less made a decision about the right way to go with balance, suspension etc so this is good progress. We also tried some new electronic maps, to try to improve acceleration, but we need to do more work on this again tomorrow.
“It's good to be fast at this stage and now we're really just waiting to go to another track, to see how this new M1 will perform there. Tomorrow we will do a long run, maybe not race distance but just quite a few laps together, which will be the final part of our work at this track."
Rossi's Fiat Yamaha team-mate and 2009 title runner-up Jorge Lorenzo is not present at Sepang due to a hand injury sustained in a motocross accident.
