Niccolo Antonelli has topped Moto3 FP2 at Sepang in an extremely tight session; his time of 2:13.583 was a hundredth of a second quicker than Czech rider Jakub Kornfeil. Conditions were hot and sunny but quite humid as cloud cover had began to blanket the circuit over the course of the afternoon. Alex Marquez posted the third fastest time finishing ahead of his primary Championship rival Jack Miller by six thousandths of a second as two hundredths covered the top four.
Efren Vazquez claimed fifth spot ahead of his countrymen Isaac Vinales and Alex Rins while Danny Kent, Enea Bastianini and John McPhee rounded out the top ten placings. Warning flags were displayed around the circuit at the conclusion of the session as monsoonal rain began to fall, the unpredictably tropical conditions emerging much earlier on in the weekend than previous years at the Malaysian circuit.
