The deadline for declaring a maximum of 24 possible gear ratios and four possible ratios for the primary gear for MotoGP class machines was fixed as the date of technical inspection for the first event of the season.
Effective 01 January 2015:
An homologation standard for racing wheels used in all classes of MotoGP events will be introduced from 2015. Final details of the testing procedure, test loads and certification procedure will be published before the end of 2012.
A proposal to permit, during the remainder of the 2012 season, the use in the MotoGP class of additional tyres with different structures was rejected.
