Despite grey clouds still circling around for the final practice session of the premier class, it was a fully dry affair that allowed riders to hone in on their race setup in the hope of an equally dry race. A determined Pol Espargaro retook his spot at the top of the timesheets and despite following his brother into the gravel trap at turn nine, he kept top spot to the checkered flag, while also showing an impressively consistent pace in the mid 1:24s. Valentino Rossi made a late jump into second from outside the top ten and did the most laps in an attempt to get nearer to the leader’s pace. Fresh off announcing his surprising departure from Ducati, Andrea Dovizioso continued his bid for a fine result at the Red Bull Ring with third place in FP4 and a steady pace to go with it.
Johann Zarco in fourth was four tenths off the lead and narrowly ahead of Maverick Vinales, followed by the Suzuki duo of Joan Mir and Alex Rins. Just a touch slower, Danilo Petrucci and Fabio Quartararo were separated by a mere thousandth of a second, while Miguel Oliveira showed the way to colleague Brad Binder. Missing out on the top ten, Franco Morbidelli and Jack Miller were seven tenths off the fastest time, ahead of Aleix Espargaro, who failed to improve on his early benchmark due to a late crash at turn nine. Cal Crutchlow in 15th was the top Honda machine, one thousandth of a second faster than teammate Takaaki Nakagami.
