Marquez sets fastest MotoGP time at COTA

Marc Marquez (Repsol Honda Team) took back the top of the timesheets at the Circuit of the Americas in Austin, Texas, as the number 93 put in a late charge on soft rubber to go fastest on Friday with a 2:04.061 – 0.296 clear of an incredible performance from Monster Yamaha Tech 3 rookie Johann Zarco. Championship leader Maverick Viñales (Movistar Yamaha MotoGP) was third quickest on combined times after topping FP1.

Nine-time World Champion Valentino Rossi (Movistar Yamaha MotoGP) shot up into the top five late in the day as riders put in some time attacks, taking P4 by 0.005 from Repsol Honda's Dani Pedrosa.

Andrea Dovizioso (Ducati Team) was sixth quickest as he looks to put his bad luck in the Americas behind him, ahead of LCR Honda rider Cal Crutchlow – who also suffered a crash in FP1.

"Today went well enough and in the second session I started to feel more comfortable on the bike," Marquez said, "but there are some areas of the setup where we need to keep working hard, especially to improve the feeling with the front. The positive is that over the course of the day, we were able to complete a lot of work and try all the tires, even the soft one, to see how the bike reacts.

"In the afternoon we also took a step forward with the electronics, finding a good enough base, although we also want to sort out some more details there to improve the bike’s behaviour on the bumps. I look forward to tomorrow, to continue the good work on the bike and on myself as well, I also can improve in T4.”

FP2 was punctuated by a big crash for Pull&Bear Aspar Team's Karel Abraham down the road from T11, with the Czech rider up and headed to the Medical Centre thereafter. Loris Baz (Reale Avintia Racing) was another crasher at T1, rider ok, and there was a mechanical problem for Team Suzuki Ecstar rookie Alex Rins early in the second session of the day – with the Spaniard back out soon after on the second bike.

Jonas Folger (Monster Yamaha Tech 3) was second fastest rookie in an impressive eighth, ahead of Octo Pramac Racing's Scott Redding and Team Suzuki Ecstar's Andrea Iannone, who completed the top ten.

Jorge Lorenzo (Ducati Team) just missed that top ten in eleventh, with Danilo Petrucci (Octo Pramac Racing), Jack Miller (Estrella Galicia 0,0 Marc VDS), Aleix Espargaro (Aprilia Racing Team Gresini) and Hector Barbera (Reale Avintia Racing) completing the top fifteen.

One big talking point on Friday afternoon saw Red Bull KTM Factory Racing unveil their first "aero-fairing" of the season, with Pol Espargaro finding the positives with the new design and nothing negative to report as the Austrian factory look to continue their progress following their first points in Argentina.

FP3 lets the grid shoot it out for direct entry to Q2 at 9:55 local time (GMT -5) on Saturday, with qualifying then beginning from 14:10.
