The key year for MotoGP will be 2027. Indeed, the goal of the Organizer and the Federation, in agreement with the Manufacturers, has been to revise the performance of the bikes with the intention of making them less powerful. Therefore, in two seasons' time, the displacements of MotoGP bikes will be downsized to 850 cc.
At the same rate, Superbikes will certainly not stand idly by, because if we continue on this path, the risk is that in two years' time the production-derived bikes may be more performant than a prototype. Given what is the situation on the horizon, Dorna and FIM, together with the manufacturers and the MSMA have voted for 2025 to revise the regulations.
For this very reason it was decided to impose a restriction on fuel flow. Until this year it was free while starting next year it will be set at 47 Kg/H with a tolerance of two grams per lap over the limit.
The calculation was made by applying a device to all the riders' bikes on the track, arriving at the decided average number. What does this mean? First of all, the engine configuration as well as exhaust and intake will have to be redone. In addition, the bikes will be equipped with an Allengra ECU that will signal how much fuel will enter the combustion chamber. Therefore, more than the amount of fuel put into the tank, it will become important how much will reach the cylinders.
What does all this entail? With the decrease in fuel, performance in delivery and acceleration will be reduced, so the bikes will take longer than before to get to maximum performance.
On the part of the manufacturers, particularly BMW and Ducati, there are some doubts, because in their view the new regulations should limit those brands that have a high number of engine revolutions: the Rossa has 16,100 while the German bike 15,500.
The fact remains that the choice in some ways takes up the path taken years ago by F1, more precisely in 2020, when it was decided that the limit should be 100 kg/h. We will see in a few months what effect that decision will have.
