Marking the first in-season test of the 2024 campaign, the MotoGP paddock remained at Jerez for an eight-hour session on Monday.

Run in good conditions, VR46 Ducati rider Di Giannantonio led the way with Maverick Vinales chasing him on the factory Aprilia.

Pramac’s Franco Morbidelli completed the top three from Spanish GP winner Francesco Bagnaia on the factory Ducati, while Alex Rins was 14th as Yamaha debuted its new M1.

Marc Marquez topped the opening hour of running after the session got underway at 10am local time, with the Gresini rider posting a 1m36.826s.

Despite not running a factory-spec Ducati, Marquez and Gresini still had much to test, with Monday’s session at Jerez the first opportunity for the partnership to evolve the bike based on the eight-time world champion’s comments from the first four rounds.

Bagnaia found his way to the top of the order in the second hour of running with a 1m36.589s, before Di Giannantonio took over at the end of hour three with a 1m36.405s.

This would stand as the benchmark for the session through to the chequered flag, with nobody troubling this as the outing came to a close.

Vinales got closest as he tested various new items, while also discovering that the bike he raced in the Spanish GP had a problem with it.

The Aprilia rider completed 80 laps compared to Di Giannantonio’s 70, while Pramac’s Franco Morbidelli was one of the busiest riders on the test day in third after 82 laps.

Bagnaia was fourth from Spanish GP rival Marquez in fifth, while Brad Binder completed the top six for KTM ahead of Aprilia’s Aleix Espargaro, Gresini’s Alex Marquez, Ducati’s Enea Bastianini and Pramac’s Jorge Martin.

Yamaha stole most of the headlines on Monday as it unveiled its radically different bike, which featured – among other things – new aerodynamics, a new chassis, swingarm and electronic settings.

Alex Rins was 14th, 0.619s off the pace, while team-mate Fabio Quartararo was 18th.

Honda also had a new bike concept to try on Monday, with Takaaki Nakagami the leading HRC runner in 16th and Joan Mir the top factory team Honda runner in 21st.
