New Repsol Honda rider Casey Stoner finished the first grand prix practice session of the 2011 MotoGP season with a 0.6sec advantage - then said he's only at 80 percent with the RC212V!
The 2007 world champion for Ducati was typically fast from almost his very first lap and was the only rider to dip below 1min 56sec.
The Australian did so on no less than five different laps, any one of which would have made him fastest, with team-mate and nearest rival Dani Pedrosa's best being a 1min 56.362sec.
"We started of where we left [at the end of testing] on Monday and used more or less the same set-up - the wind is a little stronger than we had in the test but the track condition feels pretty good,” said Stoner.
“We need to improve rear edge grip, this is an area we've struggled with a little so we need to improve that which will give us better turn in and exit from the corner.
“I'd say we're about 80% complete on the bike package, we have a few main areas we can improve, but this is always the case - you can always improve something, and if we do in these areas it will makes us a lot more confident.
“I did the whole session with the same rear hard tyre and I was happy with it from the beginning to the end, and this is good for the race.
“Finally the season has started, everything has gone fantastic so far but we need to be realistic and keep focused."
Thursday was Stoner's eleventh day on an RC212V, since his debut at last November's Valencia test. The #27 has been fastest on six of the ten days of winter testing since then.
Stoner won the Qatar Grand Prix from 2007 to 2009, and crashed from the lead last year.
