Approaching the end of the second hour and Marc Marquez posts his best time yet, on his 18th lap, of 1m 58.774s. He moves up to 4th place, as the fastest Ducati.
Ai Ogura makes progress to 11th for Trackhouse Aprilia with a mid 1m 59s. Marco Bezzecchi is still the fastest RS-GP rider in fifth.
11:42am and Alex Marquez puts his factory-spec Gresini GP26 up to sixth place. He's 0.7s behind Miller but now the fastest Ducati rider, just ahead of Francesco Bagnaia. Marc Marquez has been pushed to 9th.
For comparison, Jack Miller's 1m 58.252s is slightly slower than his 1m 57.908s best from the Shakedown, when he was fastest on Day 2 of 3.

11:30am: The top ten... Jack Miller, Pedro Acosta, Alex Rins, Diogo Moreira, Marco Bezzecchi, Toprak Razgatlioglu, Marc Marquez, Fabio di Giannantonio, Joan Mir, Franco Morbidelli.
And at the bottom of the timesheets, the slowest 5 so far are... Johann Zarco (18th), Brad Binder (19th), Lorenzo Savadori (20th), Ai Ogura (21st), Andrea Dovizioso (22nd).
Jack Miller puts Yamaha's V4 back on top with a 1m 58.252s, edging out Acosta's KTM by 0.061s.
Miller and the other Yamaha riders have the benefit of the Shakedown time, so they are expected to be strong on day one.
The bigger question is whether they will then be able to keep pace with the improvements their rivals make on days 2 and 3.
Even so, it's always good to be fast!
The latest top ten: Pedro Acosta, Alex Rins, Diogo Moreira, Marco Bezzecchi, Toprak Razgatlioglu, Marc Marquez, Fabio di Giannantonio, Joan Mir, Franco Morbidelli, Alex Marquez.
Pedro Acosta, rumoured to be on his way to Ducati for 2027, puts the latest KTM RC16 on top by 0.263s over Alex Rins.
Alex Rins started the day on the older tri-plane Yamaha front wing and remains fastest.
Fabio Quartararo had already been out on the new design (which all riders except Toprak Razgatlioglu seemed to try in the Shakedown) - and was perhaps using it when he crashed.

While most teams are secretive about their testing plans, Aprilia are refreshingly open - at least providing some details.
This is what they intend to work on today:
"After the shakedown run, Marco Bezzecchi will carry out a comparison between the RS-GP25 and the RS-GP26. After a series of checks, we will proceed with further testing of various aerodynamic solutions for the 2026 bike. A test of a new swingarm is also scheduled in the afternoon.
"Lorenzo Savadori will continue development work on several components, including some ergonomically designed solutions specifically for him. These interventions mainly focus on the general setup, both at the electronic and vehicle level."
Marc Marquez climbs to 3rd on the timesheets on his 7th lap of the year. He's now 0.7s behind Diogo Moreira and Marco Bezzecchi.
Andrea Dovizioso has suffered a technical issue with his V4 Yamaha at Turn 1.
The guys at Gold & Goose photography have sent in their first images from today's action, here are some of them:

Francesco Bagnaia.

Franco Morbidelli (2024 chassis, 2025 Ducati parts).

Joan Mir.

Johann Zarco.
Maverick Vinales and Raul Fernandez join the action, which leaves on Yamaha test rider Augusto Fernandez (who rode at the shakedown) yet to take part.
2025 Phillip Island winner Raul Fernandez has been injured at the Sepang test for the past two years, so his first task today is just to stay injury-free.
Green lights are back on and testing continues.
