The premier class made the best of their final opportunity to get a clear picture of race setup in similar, if slightly warmer conditions than expected on Sunday evening. Perhaps the standout performance came from Maverick Vinales, the Spaniard fast and consistent and edging ahead of rivals on pace. He also grabbed top spot in FP4 on his final flying lap, dethroning Johann Zarco. The Frenchman might have lost the minor honours but he also enjoyed the spotlight as he set a new MotoGP top speed record of 362.4 km/h before his Ducati made an unavoidable off track excursion.
Fabio Quartararo also showed good rhythm as he climbed into third, three tenths of a second behind the leader. Miguel Oliveira followed him closely – four thousandths of a second close – while Aleix Espargaro stayed at the business end within the top five. Despite adding Q1 to his TO DO list, Joan Mir was fast in FP4 and ended the session sixth on the timesheets. Franco Morbidelli was the odd one out on tyre choice, sampling the hard rear together with his teammate in the initial stages, but swapped back to softs and promptly climbed into seventh position.
Honda men Stefan Bradl and Takaaki Nakagami were seven tenths off top spot, while Alex Rins rounded out the top ten positions. Pecco Bagnaia and Alex Marquez narrowly missed out on that top ten, finishing just ahead of practice maestro Jack Miller, the trio little under a second down on the top time.
