Defending MotoGP world champion Jorge Lorenzo was quickest on the opening day of testing at Losail in Qatar on Wednesday.
The Spanish Yamaha driver narrowly edged out last year’s best rookie award winner Maverick Vinales of Suzuki, while the ever-present Valentino Rossi fell on his out-lap, but recovered to be third fastest on the other Yamaha.
Ducati’s Andrea Iannone was fourth on the timesheets, followed by Desmosedici riders Scott Redding, Hector Barbera and Andrea Dovizioso.
Iannone’s team-mate Andrea Dovizioso followed in seventh, while LCR’s Cal Crutchlow was the fastest Honda driver across the line in eighth.
The injured Danilo Petrucci wass the only rider not present for the test, which continues on Thursday and Friday.
Testing started at 4pm, but most waited until after sunset to replicate the conditions they will be facing in the opening race of the season.
Most of the riders also sat the final hour out, after dewy conditions led to Crutchlow and Aleix Espargaro falling in quick succession.
