Obliterating the lap record to take pole in qualifying earlier on Saturday, Martin seized the holeshot effortlessly off the line and led all 13 laps of the sprint race at Le Mans.
He headed Gresini Racing rider and chief rival for the second factory Ducati seat in 2025 Marc Marquez, who leaped from 13th on the grid and finished second after a late crash for VR46’s Marco Bezzecchi.
Aprilia’s Maverick Vinales completed the podium, fending off a late charge from factory Ducati rider Enea Bastianini to secure third – the Italian moving up to second in the championship.
Jorge Martin then won a thrilling French Grand Prix to extend his advantage at the top of the MotoGP championship standings.
The Pramac Racing rider started on pole, but was passed by Italy’s Francesco Bagnaia on Sunday’s opening lap.
The pair battled it out for the lead for much of the race before Martin, 26, moved ahead with six laps to go and powered to victory.
Six-time MotoGP championship winner Marc Marquez (Gresini Racing) – who had started 13th on the grid – then pipped Ducati’s Bagnaia for second.
