MotoGP capacity reduction to 850 cc officially confirmed
The changes of MotoGP 2027 have been clarified
MotoGP will introduce new cars from 2027, engine capacity reduced from 1000cc to 850cc.
The maximum bore will be reduced from 81 to 75 mm, which will also limit performance.
The maximum number of engines allowed per driver in a season will also be reduced from seven to six.
As announced, MotoGP will race on 100% sustainable fuel from 2027 – up from the 40% minimum the sport has raced on since 2024. As part of the new regulations, the The fuel tank will also be reduced, from 22 liters to 20 liters. , and riders will be allowed 11 liters in the Tissot Sprint.
Aerodynamics will be reduced and more tightly controlled from 2027, with the aim of minimizing their negative effects. The width of the upper part of the front apron will be 50 mm narrower and the nose will be pushed back by 50 mm, reducing the aerodynamic effect in key places, on the straights and in the braking area. This should create even closer races and even more overtaking.
At the rear, the driver’s rear aerodynamics will be part of homologation from 2027 and teams will only be allowed to update that once per season to control costs.
In the new era from 2027, all vehicle height measurement and hole shooting devices will be banned.
To further level the playing field, GPS data from all riders will be available to all teams after each session. Making data available to all competitors gives poorer performing teams and riders a better chance of progression and at a controlled cost.
The current concessions system, introduced at the end of the 2023 season, will continue – but when new technical regulations come into force in 2027, all manufacturers will start the season in Class B. They will then be re-evaluated mid-season, during the summer of 2027, and can move up or down in rankings to receive more or less incentives. This reactive system means manufacturer performance is taken into account from Day One, keeping the playing field as close as possible as the new era begins.
