MotoGP bosses have today announced the minimum brake disc size will be upped from 320mm to 340mm with immediate effect following pressure from riders in the safety commission.
The decision has been taken on safety grounds as all of the top men have been asking for this increase for some time. The 340mm discs have been mandatory at Motegi due to the heavy braking nature of the circuit.
The FIM statement reads:
The Commission 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 and at Montmelo and Sepang where 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.
