Rain disrupted both the middle and the end of the first day of the Sepang test, the riders losing three hours to a damp track. But the busiest riders still managed to record around 60 laps at the track.
Fabio Quartararo ended the day as fastest, just ahead of his Petronas Yamaha teammate Franco Morbidelli. Both riders were on the A-Spec bikes, the evolution of the 2019 machine Morbidelli will be riding in 2020. Alex Rins ended Friday as third fastest on the Suzuki, a quarter of a second behind Quartararo, and a few hundredths ahead of Cal Crutchlow on the LCR Honda.
Maverick Viñales was the fastest of the factory Yamahas despite a small crash, four tenths slower than Quartararo. Behind him in seventh, Aleix Espargaro led the Espargaro brothers, Aprilia rider Aleix a tenth quicker than KTM rider Pol. Joan Mir ended the day in ninth, six tenths off the Petronas Yamaha, and a thousandth of a second quicker than Valentino Rossi, who was tenth.
