Marc Marquez was smiling after his opening stint with Gresini, when he was sixth fastest, then jumped to second by the end of only hi🧜s third run.

Mar🌸quez's rise was complete when, at 3:20pm local time, he moved to the top of a Mot𓄧oGP timesheet for the first time as a Ducati rider.

The eight-time world champion improved further but Aprilia's Maverick Vinales - on pole at the grand prix - struck back to put the RS-GP fastest wit🐟h one hour to go, where he remained.

VR46's Marco🐲 Bezzecchi squeezed between Vinales and Marquez as the final hour got underway.

Brad Binder then broke into second place (+0.028s) for KTM in the final ten minutes and was challenging Vinales for P1 whᩚᩚᩚᩚᩚᩚ⁤⁤⁤⁤ᩚ⁤⁤⁤⁤ᩚ⁤⁤⁤⁤ᩚ𒀱ᩚᩚᩚen he was caught out by the coo♐l and windy conditions, falling at turn 5.

Raul Fernandez (being run by the Aprilia test team while a replacement is found for the RNF grid places) claimed an encouraging fifth on his debut with the 2023 machine, ahead of Alex Marquez and former Gresini rider Fabio di Gian🐻nantonio (VR46).

Enea Bastianini, Jack Miller and Luca Marini completed the♔ top ten.

Newly crowned double world champion Francesco Bagnaia (11th) and team-mate Bastianini rode a prototy🏅pe GP24 Ducaꦗti with a revised engine.

Joan Mir featured in the top ten on the 2024 Honda prototype, while n✅ew LCR rider Jඣohann Zarco suffered a mid-afternoon fall for 17th, but only +1.030s from Vinales.

Pramac Ducati's title runner-up Jorge Martin suffered an early fall, topp🔥ed the timesheets, then fell again on his way to 15th.

Yamaha had a new engine, cha💞ssis and aero (including a square♛ rear seat wing) for Fabio Quartararo (12th) and new team-mate Alex Rins (19th) to try.

KTM had a striking bla🌳ck-and-white zebra-style livery to disguise the details on a new fairing for Jack Miller, who saved a front-end scare in the final ༺hour.

Wide-eyed rookie Acosta was 18th&n🌺bsp;(+1.223s) and appeared to enjoy his debut, making some big powerslides on the R𝐆C16 and was still smiling despite a late fall.
