Effective Jan. 1, 2014, the use of the ECU and datalogger provided by the Championship organizers is compulsory in the MotoGP class. MSMA manufacturers, supplying machines for a maximum of four entries per manufacturer, will use their own electronics software but in this case are subject to a maximum fuel capacity of 20 litres. All other machines must use the ECU, datalogger and software provided by the Championship organizers and these machines may have a maximum fuel capacity of 24 litres.
The maximum number of engines that may be used in a season is limited to five engines for MSMA manufacturers’ machines (maximum four per manufacturer), nine engines for MSMA manufacturers in their first season of participation, and 12 engines for all other entries. Engines are frozen for all races of the same season.
In addition to the changes effective 2014, bore and stroke dimensions are frozen for the three-year period 2013 to 2015.
The above regulation changes are subject to the satisfactory conclusion of on-going negotiations between FIM, Dorna and the Manufacturers concerning the supply of additional machines and engines for use by other teams from 2014. Contracts for the supply of these machines, engines, parts and technical support must be concluded between Dorna and the Manufacturers prior to the first event of 2013. Only then will the technical regulation changes be finally adopted.
