MotoGP approves its revolutionary new rules

TThere are still three years left before the current rules apply. But this Monday Dorna made public numerous changes that will occur in MotoGP from 2027. They have already warned that some things will be very significant and others not so much. After many weeks of rumors, it has become possible to confirm one of the most noticeable changes in the premier category – the change in the volume of motorcycles.

According to the current rules, all motorcycles have an engine capacity of 1000 cc, and with the new rules It was decided to reduce this volume to 850 cc. This limitation is key for the safety of the riders, as the motorcycles reached very high speeds and were very dangerous in the event of an accident. Thus, in 2027 power and top speed will be reduced.

In addition, the maximum cylinder diameter will also be smaller, and the engines will become 4-cylinder and 4-stroke.

Aerodynamic limitations

Today, the most defining area is aerodynamics. Factories, especially European ones, are constantly finding new ways to gain time through aerodynamics in 2027. Dorna wants to control this part of the motorcycles on the grid and will ban some devices that are used on some motorcycles in current regulationswhich also limits future escalation like the one seen now.

All these aerodynamic restrictions will directly affect the width of many MotoGP surfaces.. The front fairing’s aero housing will be reduced from 600mm to 550mm, with a maximum width of 50mm. As for the rear end of the bike, it must be homologated as part of the Aero Body, and teams will only be able to make one update or improvement per season to improve competitiveness.

The minimum weight of the motorcycle will also be affected.. Under the new rules, top category motorcycles will have to weigh a minimum of 153 kilograms and have a fuel tank capacity of 11 liters for the Saturday sprint and 20 liters for the Sunday race.

Height devices, outside

One of the biggest bans will concern high-altitude devices. The holeshot device or any height measuring device that all drivers use at the start to avoid wheelies will not be permitted. So in 2027, pilots will have to change the start procedure.

Concessions remain

Another part of the rules that has undergone many changes is the revised concessions. Manufacturers competing in 2026 will have a mid-season review and another at the end of the course, called the “B” period. New manufacturers who come into effect under the new rules will have a “D” period and will be required to undergo inspections every six months.

Thus, D-rank manufacturers will have two more engines available during the season. Those in the ‘B’ rank will see the number of engines reduced to 6 in 20 Grand Prix seasons, although there will be more if there are more races. Since this technical announcement has already been published, manufacturers will have more than two years to understand the new rules and develop new prototypes.
