Casey Stoner completed his and Honda's domination of the Sepang test with the quickest time on the final day on Thursday. The Australian, who had been fastest on the first two days, continued with his impressive preseason form by finishing on top of the times with a lap of 1m59.665sec.
Stoner finished ahead of teammate Dani Pedrosa yet again, the Spaniard the only other man to break the two-minute barrier.
"We had a good day comparing the chassis again and I'm happy we have made our decision on which one we'll use for the season," said Stoner. "We also tried a lot of electronics with engine braking and found improvements in a few areas, and some losses in others, so we need to rectify these.
"The chassis we've chosen always behaves in the way we want it to, no matter what setup we use, we are also able to adapt it fairly easily. So, when we get to Qatar in a few weeks, we'll be able to test different setups at the same time and get more track time on it.
"Some changes can be quite time consuming to do, so having the two bikes with identical chassis will be useful. The test here has been very productive for us, we did a long run here today – almost race distance – and gathered some key information. I'm feeling more and more comfortable on the RC212V and I can't wait to get to Qatar."
Gresini's Marco Simoncelli posted a promising third fastest time, with Andrea Dovizioso on the third works Honda in fourth to complete another dominant day for the Japanese manufacturer.
Ben Spies was the first non-Honda rider with the fifth-quickest time on the Yamaha, but the American was a full second off the pace set by Stoner.
MotoGP champion Jorge Lorenzo was seventh on the the other works Yamaha, while Valentino Rossi was back in action after having to miss yesterday's session because of the flu. The Ducati rider finished in 11th nearly two seconds off the pace after 59 laps.
