Franco Morbidelli topped Free Practice 1 at Misano as Yamaha’s V4 engine debut was marred by electronic problems.
The Pertamina Enduro VR46 rider set a 1m31.342s to lead the timesheets before crashing at Turn 10 late in the session.
Morbidelli had been forced to sit out the opening ten minutes due to a penalty carried over from Barcelona, but immediately climbed the order once on track.

His lap was enough to secure top spot, 0.249s clear of factory Yamaha’s Fabio Quartararo, who improved on his final lap to secure second.
VR46 team-mate Fabio Di Giannantonio followed in third, just 0.005s off Quartararo, ensuring both Ducatis from Valentino Rossi’s squad featured inside the top three.
Alex Marquez slotted into fourth for Gresini, while Marc Marquez rounded out the top five on the factory Ducati.
Honda’s Luca Marini placed sixth ahead of KTM’s Pedro Acosta, who could not match his Barcelona form but still led the charge for KTM.
Marco Bezzecchi was eighth for Aprilia, with Trackhouse rider Raul Fernandez ninth. Reigning champion Jorge Martin completed the top ten on the second factory Aprilia.
Behind them, Francesco Bagnaia endured a muted session in 11th, while Joan Mir was the second Honda in 12th.
Jack Miller and Miguel Oliveira both placed outside the top ten on the Pramac Yamahas, with Oliveira also suffering two separate crashes.

Further back, Augusto Fernandez completed the new Yamaha V4 prototype’s first laps in an official MotoGP session, but a technical issue mid-session limited his mileage. He finished 21st, 1.195s off the pace.
Yamaha confirmed after the session that they were hit by electronic issues, which they were still analysing to find the reason for.
The first session of the San Marino GP might be an early indicator for just how close the fight for the podium could get this weekend, with P1 and P6 being separated by just 0.022 seconds.
