Prima Pramac rider Jack Miller was the fastest in the first free practice session (FP1) for the Valencia MotoGP at the Ricardo Tormo Circuit, Valencia, Friday.
Miller dominated the session and outpaced Track House driver Ai Ogura.
The session was delayed for quite a while because a red flag was waved during Moto2 free practice.
Alex Marquez immediately performed well from the start of the session and was untouchable at the top of the list of fastest riders throughout the middle of the session.
