Due to inclement weather forecast on 22 October, the schedule for the MotoGP sprint and main race was swapped, with the main race being held on 21 October, while the sprint was scheduled to be held on 22 October.[1] For the first time since the 2015 Dutch TT, the MotoGP race was held on Saturday. Both the Moto2 and Moto3 were held on 22 October, with both classes having a warm up session introduced. All races on 22 October also started an hour earlier than planned to avoid the inclement weather.[2]
Álex Rins withdrew from the rest of the weekend due to persistent right leg pain.[24]
Moto2
The race was scheduled to be run for 23 laps, but was red-flagged race after 9 full laps due to inclement weather and bad track conditions. As less than 2/3 of the race distance was completed, the race was to be restarted for 6 laps. Eventually, race direction decided not to restart the race as track conditions were not improving. Per regulations, half points were awarded after failing to complete half of the original race distance.[25]
