Maverick Vinales continued to underline the GSX-RR’s impressive pace as he set the quickest lap for Suzuki on the second night of pre-season MotoGP testing at Losail.
The Spaniard’s time of 1m55.436s – set on his 28th lap – was the fastest of the week so far, and put him ahead of 0.072s clear of Ducati’s Andrea Iannone.
Wednesday’s pace setter and reigning world champion Jorge Lorenzo followed in third place, 0.099s behind for Yamaha.
Lorenzo’s team-mate Valentino Rossi was slower, crossing the line in eighth place.
Vinales’ team-mate Aleix Espargaro was the first to test out the new ‘spec 2’ version of Suzuki’s seamless gearbox, which has seamless downshifts as well as upshifts. He was 10th quickest on the day.
Honda’s Marc Marquez overcame a fall at turn one on his fifth lap of the evening, recovering to post the ninth-fastest time.
His team-mate Dani Pedrosa was marginally quicker, coming home in seventh.
Like the day before, most riders waited until after sunset before heading out for their first laps.
The test wraps up on Friday, ahead of the start of the season at the same circuit on March 17.
