At the Dutch TT, Quartararo claimed his fourth win of the season, extending his lead in the riders' championship heading into the summer break, with a 34-point-advantage over his nearest rival and compatriot Johann Zarco.

[11] At Misano, Bagnaia repeated his feat to win from pole for the second consecutive race, cutting the Frenchman's lead to just 48 points with four rounds remaining.
[12] In Austin, Marc Marquéz topped the podium for the second time of the year, ahead of chief title contenders Quartararo and pole-sitter Bagnaia.
[14] While Quartararo fought his way back into the top five, Bagnaia crashed from the lead with four laps remaining, gifting Marquéz his third win of the season.
