The 2027 MotoGP regulations will introduce several significant changes, most notably the reduction of engine displacement from 1000cc to 850cc. Additionally, aerodynamics will be simplified, and ride height devices will be banned. Adjustments will also be made to fuel tank capacity and the concessions system. Here’s a detailed breakdown of the new regulations:

Engine Specifications: Engine displacement will be reduced from 1000cc to 850cc, and the maximum cylinder bore will decrease from 81mm to 75mm. Engines will continue to be four-cylinder and four-stroke only.

Rankings and Concessions: Manufacturers that competed in 2026 will start the 2027 season in Rank B. Rankings will be revised at the mid-season checkpoint based on results from the 2027 season only; results from the 2026 season will not be considered. The regular ranking system will resume at the end of the 2027 season. Manufacturers that did not race in 2026 will begin the 2027 season in Rank D, with rankings revised mid-season based on the first half of the 2027 season.

Engine Allocations: Each permanent rider will have access to six engines per season for a 20-race calendar, or seven engines for a 21 or 22-race calendar. Manufacturers in Rank D will be allowed two additional engines per rider per season.

GPS Data: GPS data from all riders will be shared with all teams at the end of each session.

Gearbox Regulations: The total number of permitted gearbox ratios will be reduced to 16, with four overall ratios for the primary drive each season.

Bike Weight: The minimum weight for MotoGP bikes will be reduced from 157kg to 153kg.

Ride Height Devices: No ride height devices, including holeshot devices for race starts, will be allowed.

Fuel Tank Capacity: Fuel tank capacity will be limited to 20 litres for Grand Prix races and a maximum of 11 litres for sprint races.

Aerodynamics Restrictions: The maximum width of the high portion of the front fairing will decrease from 600mm to 550mm, the maximum rear end height will drop from 1250mm to 1150mm, and the foremost point of the front fairing will be moved back by 50mm. The rearward taper of the front fairing aero appendices will also narrow. All aero components behind the rider must be homologated as part of the aero body, with manufacturers allowed one update per season.

Fuel: Starting in 2027, the use of 100% non-fossil origin fuel will be mandated. The FIM, in collaboration with the manufacturers' association and MotoGP’s fuel suppliers, will provide further technical details through the TWG1 working group, which includes representatives from Dorna and the teams’ association, beginning in April 2024.
