World championship leader Quartararo seals his fifth pole position in a row for the Catalunya MotoGP at Barcelona.

Miller snatched second behind the Frenchman then walked away from a big highside though Turn 3.

Zarco will complete Sunday's front row start despite a close moment with Binder, whose KTM team-mate Oliveira heads row two.

Rossi fell early in Qualifying 2 at Turn 4, while chasing team-mate Morbidelli, and had to get a scooter ride back to the pits before returning on his spare bike. Pol Espargaro  fell at the end of the session.

Marc Marquez didn't progress past Qualifying 1, despite a tow from Miller on both runs, after Repsol Honda team-mate Espargaro in-turn grabbed a tow behind the #93.

Alex Rins is absent after suffering a wrist fracture while training at the track on his bicycle on Thursday morning.

Vinales is working with new crew chief Silvano Galbusera for the first time this weekend, having split form Esteban Garcia following Mugello.

Turn 10 in Barcelona has been redesigned in time for this year's MotoGP event, with the sharp 'F1 corner' at the end of the back straight replaced by a more flowing layout similar to the original Turn 10, used until 2016.

Rookie Jorge Martin is back this weekend after missing the last three rounds due to multiple fractures in Portimao.

Marc Marquez is taking part in his fifth event since returning to MotoGP action, but continues to struggle with his right arm and shoulder.
