Fabio Quartararo will not score points at the Dutch Grand Prix before MotoGP's summer break.
On lap 14, the world championship leader made a mistake on the exit of the corner when going over the gas, which propelled him above his handlebars.
The Yamaha rider has finished his glide in the gravel.
He was then able to return to his pit without apparent injury but was forced to retire.
A very bad Sunday for the Habs who had suffered a first fall on the fifth lap, after trying to overtake in a bend.
Quartararo, with a 34 point lead in the championship over Aleix Espargaro, will in any case remain the leader after this Grand Prix.
