Restart, tyre, engine tweaks in MotoGP rules
More tyres available for MotoGP's new Michelin era, plus quicker restarts and a new formula for freezing engine specifications...
A meeting of the Grand Prix Commission in Madrid saw the following changes agreed to the MotoGP Sporting and Technical rules.
They include an increase in the tyre allocation for the new Michelin era. This will see the number of slicks rise from 21 to 22 due to an extra rear, while wets will rise from 5 front and rear to 7 of each. Riders will also have 3 front and 3 rear of the returning intermediate rubber.
The engine regulations, which prohibit in-season development, have also been tweaked so that factories can freeze a greater range of engine specifications the season after losing technical concessions.
This currently only refers to Ducati, which will not have concessions next season and is to support a range of Desmosedici machinery at Aspar, Avintia, Pramac and its own factory team.
With the single ECU now compulsory, all references to 'Factory' or 'Open' class have now been removed from the rules...
Re-Starting Interrupted Races
In order to minimise the time taken to restart an interrupted race a new procedure has been approved for all classes. This will involve a shorter time spent in the pit lane before the new sighting lap and a significantly shorter countdown on the grid prior to the warm up lap. (Engines will not be stopped and only one mechanic per rider will be permitted onto the grid).
In the Moto3 and Moto2 classes when there is more than one race interruption the length of the restarted race will always be 2/3 of the previous race, with a minimum of five laps. So, for example, if the first restarted race was 2/3 of the original race distance then the distance of the second restarted race would be 2/3 of that distance – always with a minimum of five laps. In situations where a restarted race has been interrupted after less than five laps then the distance for the next race will be determined by Race Direction with a minimum of five laps.
For all classes the regulations have been amended to ensure that when a rider uses a machine of the same capacity as the relevant MotoGP class, this can only be a standard production road-homologated machine.
Penalties for Using Engines over Allocation
In the Moto3 and MotoGP classes, where more than one extra engine is taken at a single event then penalties for the second and any subsequent extra engines will be carried forward to the next event(s).
Rider's Safety Equipment
Following consultation with all major suppliers of helmets, leathers, boots, etc., new regulations have been approved covering the specifications of equipment used by riders. Procedures for control and testing were also approved.
MotoGP Class Tyres
In line with the appointment of Michelin as the Official Tyre Supplier, the allocations of slick tyres have been modified. Riders will now be permitted to use a maximum of 22 tyres (10 front and 12 rear).
For wet tyres the allocation is a maximum of 7 front and 7 rear.
Riders will now also have the option of an intermediate tyre with a maximum allocation of 3 front and 3 rear.
Engine Allocations – MotoGP Class
It has already been agreed that manufacturers can homologate three different engine specifications which may be used by different riders during the season. It has now been agreed that manufacturers who lose “concessions” may homologate additional engine specifications for the first season after losing those concessions. However, the maximum number of different specifications is related to the number of Satellite teams being supplied. The formula to be used to calculate this number is:
One Factory team + 2 Satellite teams = 3 different specifications
One Factory team + 3 Satellite teams = 4 different specifications
One Factory team + 4 Satellite teams = 5 different specifications
MotoGP Class – Effective Immediately
Previous regulations made frequent reference to “Open” and “Factory” classes and machine types. All such references will now be removed.
Moto2 Class Regulations
Teams will be able to refer to the FIM website to check a list of approved dataloggers and sensors.
The regulation concerning throttle control has been clarified to specify that the control valve must be exclusively controlled by mechanical means, i.e. twistgrip and cable.
Moto3 Class Regulations
Regulations already exist which define which certain chassis parts are “performance parts” and need homologation. The regulations have been modified to state that only homologated parts can be used at events.
Only the oil provided by the official supplier may be used in all parts of the engine including crankcase, gearbox and clutch.
Official Fuel Supplier for Moto3 and Moto2
The appointment of the Total/Elf company as the official, exclusive supplier of fuel was approved.
Grand Prix Medical Code
An updated and revised Medical Code, produced by the FIM in consultation with other MotoGP medical staff, was approved.
