About to enter the final five minutes of FP1 now, still Acosta fastest but the final runs are underway for everyone.
Improvement from Marc Marquez, stays third but down to a 1m30.1s.
Nakagami, here replacing the ill Mir, touring at turn four, getting in Zarco's way. It's Nakagami's first race since last year.
Bezzecchi runs in deep at the chicane, almost hit Martin so opted to bail on the corner. P6 at the moment for the Italian.
Martin up to second now, 1m31.159s. Acosta still the only rider in the 1m29s after almost 25 minutes of FP1.
Martin improves early on his second bike, 1m30.454s puts him fourth and 0.6s behind Acosta.
Martin back out on track; he's the only rider out there at the moment. Everyone else preparing their run two.
Acosta back in the pits now after that first run, some problem towards the end of that run but not entirely clear what.
Marc Marquez now up to second but still 0.4s behind Acosta.
Acosta the first rider into the 1m29s today, he's now 0.657s clear of Bezzecchi at the top.
Perhaps Espargaro was right...
Technical problem for Martin after eight minutes. Just ground to a halt exiting turn four.
It's Acosta setting the early pace in Austria ahead of Bezzecchi, who spoke yesterday of how "painful" it was to analyse with the Aprilia team his turn 13 crash last Sunday.
Pit lane is open and we are underway for FP1 at the Austrian GP.
Nakagami: Honda 850 “quite competitive”, 1000cc MotoGP return a “big shock”

Moto2 FP1 has just finished in Austria and the first MotoGP practice of the weekend is just a few minutes away. Some low cloud around, but it's a dry track.
Some big crashes in that Moto2 session, especially for Angel Piqueras, Adrian Huertas, and Collin Veijer.
Keep an eye out for the penultimate corner in this one as well - Guido Pini crashed there while trying to pit in Moto3 FP1, Rico Salmela lost the front but saved it doing the same thing, and Manuel Gonzalez had a moment there in Moto2 FP1.
Ai Ogura is back for Trackhouse this weekend. The Japanese rider has been absent since a crash before the Aragon GP three weeks ago.
Speaking yesterday, he said it was a mistake to go along with advice from doctors who said he should avoid surgery on his injury left hand.

KTM is the only manufacturer other than Ducati to have won a race at the Red Bull Ring, although the last one came in 2021.
Pol Espargaro suggested yesterday that this weekend will be one of the best chances for Pedro Acosta to take his own maiden premier class victory.
Acosta played down his chances in the pre-event press conference, although he did admit it would be a "perfect way" to end his time with KTM.

Alex Rins announced at Misano that he will stop racing motorcycles full-time at the end of this year.
It was immediately rumoured that he will head to four-wheel racing in 2027, although in what capacity it currently unclear.
F3 was put forward as a somewhat surprising possibility by Rins yesterday, the Spaniard having also been linked with the Dakar Rally.

The candid conversation between Francesco Bagnaia and Fabio Di Giannantonio after the race at Misano last weekend that was captured and published by Spanish MotoGP broadcaster DAZN has been criticised as "totally disrespectful" by Bagnaia ahead of this weekend's Austrian race.
Di Giannantonio also talked about it yesterday, saying it was "unfair".

Austria is home to the third-largest community of Turkish citizens - outside of Turkiye - in Europe. As such, there is a strong contingent of Turkish fans at the Red Bull Ring this weekend supporting Toprak Razgatlioglu, which the MotoGP rookie said yesterday made him "excited" for the weekend.
Full story here.

Welcome to live coverage of today's MotoGP practices from the Red Bull Ring, where FP1 is due to start in just over 40 minutes at 10:45 local time.
