Andrea Dovizioso put Ducati on top of the timesheets during the opening night of the final official MotoGP pre-season test, at Losail in Qatar on Friday.

The Italian bounced back from a difficult Phillip Island test to hold off Maverick Vinales - who has been fastest overall at all previous tests since joining Yamaha - by 0.360s.

Testing began at 4pm and concluded at 11pm, although most riders waited until sunset (6pm) before heading out on track.

Marc Marquez then gave Honda's new winglet fairing its public debut at 8pm, but fell moments later at the final corner.

Red flags came out in the final hour after timing screens suggested Marquez, Pol Espargaro Alex Rins and Lowes fell at almost the same time, in what appear to have been separate incidents.

Dew, which forms on the surface of the track late at night in Qatar, was the chief suspect. Due to the red flags, there were no changes in best lap times during the final hour.

Espargaro, like Marquez, had also fallen earlier in the evening. As did Suzuki's Andrea Iannone.

Tito Rabat is returning from an injury at Sepang, but Hector Barbera is missing the test after fracturing his collarbone in a training accident.

Testing continues on Saturday and Sunday, with the opening race of the new season being held at the same venue on March 26.
