The MotoGP championship is preparing for a significant transformation beginning in 2027, as the Grand Prix Commission—including Dorna, IRTA, MSMA, and FIM—has confirmed new technical regulations that will reduce engine displacement from 1000cc to 850cc. This change is part of a safety-driven strategy to control the ever-increasing power and speed of the machines, a move strongly supported by Gigi Dall’Igna, CEO of Ducati Corse.
It is important to reduce the power and speed of the bikes. If we continue to increase them, the tracks would no longer be safe. That’s why I believe it’s right to take a step back,
stated Dall’Igna in an interview with Speedweek.
Details of the New Engine Regulations and Impact on Performance
The updated rules also set a strict limit on cylinder bore size, reducing it from 81 mm to 75 mm, which brings an end to the era of 1000cc four-stroke prototypes that has defined MotoGP since 2012. Despite this reduction, Ducati is expected to remain competitive, with Dall’Igna underscoring that the 850cc engine represents a balanced compromise among several options evaluated by engineers.

Additional Regulatory Changes Beyond Engine Downsizing
The overhaul extends beyond engine size, introducing a lower fuel capacity limit—20 liters for longer races and just 11 liters for sprint events. Modifications to suspension rules will remove front-lift and ride-height adjustment devices, while aerodynamic components will be scaled back to reduce disruptions within the race pack. Furthermore, MotoGP will switch tire suppliers, adopting new Pirelli tires that promise to add a fresh dynamic to the competition.
Concerns About Performance Gap and Classification
Some experts have expressed worry that the reduced engine output might narrow the performance difference between MotoGP prototypes and production Superbikes on certain tracks. Dall’Igna dismissed these concerns, highlighting the importance of clearly defined regulations for both classes to preserve the distinct identity and challenge presented by top-level MotoGP racing.
Significance of the 2027 Rule Changes for the Future of MotoGP
This set of regulations aims to curb the relentless technological escalation of previous years without compromising what makes MotoGP unique. According to Dall’Igna, these measures offer an opportunity to rethink the sport’s direction, focusing on safety, fairness, and excitement for fans and riders alike. The transition to 850cc engines marks a pivotal chapter in MotoGP’s evolution, with Ducati and other teams preparing to showcase new strategies under the updated framework as the 2027 season approaches.
