MotoGP, A hit on the curb responsible for Bastianini's bent rim

In the image taken by Sky Sport here is the bent rim in the impact with a curb that resulted in Bastianini's retirement. It was not a technical problem, but simply an unfortunate event.

Of course at the point where it bent the rim let the air escape from the tire resulting in Enea's retirement.

His mechanics, sympathetically, labeled him to avoid confusing him with the healthy ones!
