For his half, Joan Mir, within the lead earlier than the interruption of the race, was additionally utilizing the small discs however had not encountered any issues.

Regardless of his lack of accountability on this accident, Brembo developed a brand new braking system to enhance security on essentially the most demanding tracks such because the Purple Bull Ring. These new cash are additionally anticipated for use in rounds of Motegi, Buriram and Sepang, scheduled for the autumn.
