2023 Indonesian MotoGP: Friday Practice - LIVE UPDATES

man of the moment Jorge Martin leapfrogs ahead of the Aprilias to take over the top spot for Pramac Ducati. Martin is the first rider to break the 1m 32s barrier this weekend.

Meanwhile, the injured Bezzecchi jumps to fourth place!

Alex Marquez falls at Turn 1. The Spaniard is on his feet but cannot lift his bike due to the recent rib fractures.

7mins to go: Vinales, A.Espargaro, Bagnaia, Marini, Bastianini, di Giannantonio, Quartararo, M.Marquez, Martin, Miller.

... and now Fabio Quartararo also has to sit up after his rear tyre kicks out through Turn 7, where Marc Marquez crashed last year.

Alex Marquez has a scare on his Gresini Ducati, almost a replica of brother (and future team-mate) Marc's earlier save.

Impressive early speed from Marini and di Giannantonio who are up to fourth and fifth, behind Bagnaia.

Either way, it's now looking very much like Catalunya with Aleix Espargaro slotting into second behind team-mate Vinales.

Francesco Bagnaia briefly blasts to the top with a soft front and medium rear tyre combination, before Vinales responds to pull half a second clear.

The Aprilia excelled in low grip at Barcelona, but the RS-GP riders insisted the change of tyre construction means it's not assured the same will happen this weekend.

While all riders are using the medium compound rear tyre, the full range of soft, medium and hard fronts are in use this morning.

Big scare for Marc Marquez who lost the rear of his Repsol Honda on corner entry, reviving memories of last year's massive highside that put him out of the race and caused another episode of diplopia. This time Marquez keeps control, albeit running off track.

Bezzecchi is climbing up the order, he is now 17th and +1.789s from Vinales. Team-mate Luca Marini remains the fastest of the injured riders returning this weekend, in 9th.

Halfway through the session - top 10: Vinales, Quartararo, Miller, Martin, M.Marquez, Oliveira, A.Espargaro, Binder, Marini, Morbidelli.

World championship leader Francesco Bagnaia is only 15th at present.

Vinales is currently the fastest with medium-medium tyres but Quartararo, Miller, Martin and Marc Marquez are trying the hard front, which has a stiffer construction.

Bezzecchi fights on. The MotoGP doctor gestures to Bezzecchi to ask if he wants to stop, Bezzecchi shakes his head 'no' and returns to the track.

Miguel Oliveira becomes the first MotoGP faller of the weekend, losing the front at Turn 11. The RNF rider is currently 5th fastest.

Marco Bezzecchi has done a six-lap run and is then seen in deep conversation with the VR46 team and MotoGP doctors.

Vinales moves the goal posts again in P1 with Quartararo and Marc Marquez now best of the rest.

Quartararo, who has high expectations for this weekend due to the unusual rear tyre needed in the Indonesian heat, is up to second, 0.4s behind Vinales.

10mins gone and it's Aprilia's Maverick Vinales fastest with a 1m 33.200s followed by Marc Marquez and Miguel Oliveira.

5minutes gone and Alex Marquez now joins his rivals out on track.

Riders are leaving black lines as they put the power down on the exit of the dusty corners.

Alex Marquez, returning from rib fractures, is in no rush to head out and is watching his rivals from the Gresini Ducati pits.

The green flags are waved and the 45-minute session begins.

Although passed fit to ride this morning, Bezzecchi will need a further medical check after this morning's session.

Meanwhile, a sore Marco Bezzecchi is carefully zipping his leathers over a bandage covering his freshly fractured right collarbone. The Italian only arrived at Lombok at 7:50am local time this morning.
