Marco Simoncelli was the surprising pace-setter on the final day of MotoGP testing at Sepang on Thursday.
The Gresini Honda rider posted a best time of 2m00.757s, the best time of the three days of testing at the Malaysian circuit.
Simoncelli was followed closely by a group of riders who also broke into the 2m00s bracket, with Casey Stoner just 0.054 off the Italian's pace on the works Honda.
World champion Jorge Lorenzo was also less than a tenth behind the leading bike on his Yamaha.
Andrea Dovizioso on the second works Honda, and Ben Spies on the Yamaha completed the top five, with yesterday's pace-setter Dani Pedrosa down in sixth position.
Valentino Rossi finished down in 10th as he continued to acclimatise to the new Ducati, the Italian around three tenths of a second slower than team-mate Nicky Hayden.
Suzuki rider Alvaro Bautista was sidelined from the final day of testing after feeling unwell, the Spaniard replaced by Noburu Aoki.
"I am not feeling well at all, I have a constant feeling of sickness and it hasn't improved all day," said Bautista. "I tried to ride the bike this morning; I really wanted to use the good track conditions and try to do my first 2'00 minute lap-time of Sepang!
"But immediately I made the first lap, the physical effort made the sickness worse and it was just impossible. So, I must say sorry to the team and I am also very disappointed for myself."
