Following Sunday's season-ending MotoGP race, riders and teams have returned to the Valencia circuit to start their 2020 preparations in earnest during a two-day official test.

Moto2 champion Alex Marquez - who will join brother Marc at Repsol Honda next season - has been placed at the LCR team for this test and is on track alongside fellow rookies Brad Binder and Iker Lecuona.

Miguel Oliveira and Takaaki Nakagami are not present, as they continue to recover from shoulder surgery, while Francesco Bagnaia is absent after his bizarre pit lane accident on Saturday. Danilo Petrucci had to stop testing after just ten laps on Tuesday due to tendonitis in his shoulder.

Dani Pedrosa is back in action as part of his KTM test riding duties.

Outgoing rookie star Fabio Quartararo led an all-Yamaha top three on Tuesday, with Andrea Dovizioso (Ducati) and Marc Marquez (Honda) best of the rest. All factories with the exception of Aprilia, whose new bike will not be seen until Sepang in February, have brought significant updates to this test.

The Wednesday action was briefly interrupted at 12:30pm when Iannone's Aprilia engine blew-up on the main straight, leaving his bike in flames.

Testing takes place from 10am to 5pm.
