Overview
- LCR Honda’s Johann Zarco set a 1:21.257 to top the decisive Practice, ahead of Marc Marquez and Yamaha rookie Toprak Razgatlioglu, with Jorge Martin and Pedro Acosta completing the top five.
- Direct Q2 spots went to Zarco, Marquez, Razgatlioglu, Martin, Acosta, Alex Marquez, Fabio Quartararo, Fermin Aldeguer, Francesco Bagnaia and Ai Ogura after rain halted further improvements.
- Thailand winner Marco Bezzecchi and Raul Fernandez must fight through Q1 after struggling in the mixed conditions, with early crashes affecting Jack Miller, Brad Binder and home rookie Diogo Moreira.
- An hour-late FP1 ran on a drying track with Pedro Acosta fastest on wet tyres following days of flooding and a major clean-up at Goiânia, and the planned extended running was cut back by delays.
- Teams face a short, fast and unfamiliar circuit with dusty red-soil run-off and an enlarged Michelin rear-tyre selection, and forecasts point to more showers that could shape qualifying and the race.
