2019 MotoGP San Marino Grand Prix Live: As it happened.

Halfway through Moto2 FP1 and it's Nagashima quickest by 0.194s from Marquez. Luthi, Lowes and Vierge complete the top five.

Binder arrives back at the KTM garage, but no bike yet so he won't be on track for a while.

Big accident for Brad Binder at the start of Moto2 FP1 at Misano.

Jack Miller has also fallen, the Australian tumbles after losing the front at Turn 8.

Fall for Rabat who highsides as he passes Lorenzo, the Avintia rider gestures that he's not happy with the Repsol Honda rider.

Quartararo has a scare through the ultra-fast Turn 11, his feet off the footpegs.

Into the final minute of FP1 and Quartararo pulls 0.376s clear of Marquez. Vinales third and wild-card Pirro fourth.

Valentino Rossi has been on track with the new carbon fibre swingarm on his Yamaha, which he first tried at the Misano test. The home star is currently 9th.

Lorenzo, who halted testing early due to inflammation from his back injuries, is only 22nd at present.

Rossi improves to fifth, 0.5s from Quartararo.

Some take a few laps to find the limit on a Friday morning!

15 of the 45 minutes gone and Quartararo remains quickest, now by 0.059s from Marquez. 

Vinales, Pol Espargaro, Petrucci, Rins, Pirro, Rossi, Dovizioso and Miller complete the current top ten.

"It's so physical. In all of these tight turns, you've got to have a lot of confidence in the front!"

Now test leader Quartararo hits the front. The French star won't face as much 'rookie disadvantage' as usual due to set-up time from the test.

Five minutes gone and it's Marquez fastest from Pol Espargaro and Rossi.

Opening MotoGP practice begins at Misano...

Next up it's MotoGP FP1.

Rookie Fabio Quartararo was fastest on both days of the recent test, but grip levels were low after recent track cleaning to remove excess rubber from the surface.

A lot of bikes have been on track to try and rebuild some grip since and the Moto3 riders were only half-a-second from race lap record pace this morning.

Moto3 FP1 - Results: Arenas, Antonelli, Rodrigo, Arbolino, Dalla Porta, Canet, Fenati, McPhee, Ogura, Salac...

While Toba is undergoing checks on his feet after the highside, Arenas is now fastest from Antonelli and Rodrigo.

Dramatic highside for current leader @KaitoToba!

Thankfully, the @honda_team_asia rider is back up on his feet! #SanMarinoGP pic.twitter.com/ayC8unEjNb
