Crash.net is at Losail in Qatar for this weekend's second and final official MotoGP pre-season test.
Maverick Vinales was fastest on the opening night for Yamaha ahead of Suzuki's Alex Rins, with Ducati's Andrea Dovizioso making it three manufacturers in the top three.
LCR's Takaaki Nakagami was the surprise top Honda in eighth, Pol Espargaro the lead KTM in ninth and Aleix Espargaro top Aprilia in twelfth.
Jorge Lorenzo, who missed Sepang due to a fractured left scaphoid bone in a January training accident, is returning to action under the floodlights and riding in Repsol Honda livery for the very first time.
Team-mate and reigning five-time champion Marc Marquez, who underwent a shoulder operation in December, said he felt much stronger on Saturday than at the previous Sepang test.
Testing takes place from 4pm to 10pm.
