The Grand Prix Commission has unanimously decided, in the interests of safety, to modify the regulation concerning the front carbon disc brake sizes in the MotoGP™ class.

Currently the regulations permit two sizes of front carbon discs; 320 mm discs must be used at all circuits except at Motegi, where the use of 340 mm discs is mandatory, whereas at the Circuit de Barcelona-Catalunya and Sepang the use of 340 mm discs is optional.

Following a recommendation from the Safety Commission and with the support of the brake manufacturers, it has been decided that the use of 340 mm disc brakes will be optional for all circuits with the exception of Motegi where such use remains mandatory.
