Taunted by intermittent rain on Monday, Casey Stoner put in 65 laps of the Qatar MotoGP circuit during the final night of a private Ducati test.
“Today wasn’t too bad but I’m knackered!” said the retired double world champion. “We got a lot of track time, even though the conditions weren’t perfect.
“There was a bit of rain, but then it was dry for the rest of the day, and there was more than enough time for us to complete the scheduled programme.”
The main purpose of Stoner’s second test since returning to Ducati was to make his debut on the 2016 Desmosedici, which Andrea Dovizioso took to second place in Sunday’s season-opening race.
“Finally, I got some time on the  Desmosedici GP, which I found different to the GP15,” said Stoner, who cited a ‘softer, more forgiving’ chassis as among the main changes with the new bike.
“I would have loved two days to test the bike thoroughly, but we are happy with what we did in the 65 laps.”
The #27, who revealed his main role at the moment is testing new parts that factory riders Dovizioso and Andrea Iannone don’t have time to try on a grand prix weekend, added:
“We tested lots of stuff, there were positives and negatives in everything, and we were quite happy with the direction we are taking.”
Ducati did not release lap times.
Stoner ruled out replacing injured Pramac rider Danilo Petrucci on the opening night of testing. The date of his next test is not yet known, since it will depend partially on the completion of new parts.
Ducati development rider Michele Pirro, not present at Losail, is expected to stand-in for Petrucci at round two in Argentina.
