The Grand Prix Commission has now written MotoGP’s 20,000rpm ceiling directly into the class regulations and immediately prohibited practice starts from pit-lane exits at every circuit. The decisions affect the running of Grand Prix weekends as well as the technical direction of the championship’s next-generation machinery.

The limit was already coded into the official ECU software; the rulebook entry is intended to remove any ambiguity. Crash.net reports that current 1000cc MotoGP machines normally reach around 18,000–19,000rpm. Next season, engine capacity will drop to 850cc and cylinder bore will be reduced from 81 to 75 millimetres. The combination is designed to discourage engine concepts aimed at exceptionally high revs.

A new route for practice starts

Pit-lane practice starts had previously been permitted at slightly more than 30% of the circuits on the calendar. They are now banned everywhere. Dedicated practice-start zones have been introduced across the calendar, and every Grand Prix will also include a separate MotoGP practice-start session.

Moto2 will begin its 2027 season with every team outside the concessions system. The new engine specification will require new chassis, while the performance ranking will be reassessed for the first time at mid-season. Each chassis manufacturer may make one update either to its chassis or swingarm during the season. Aerodynamic bodywork will stay on the 2026 designs, and the number of older designs available for use will be restricted to keep costs under control.

The move to 100% non-fossil-origin fuels in Moto2 and Moto3 has been delayed. The timing is being coordinated with Triumph’s new Moto2 engine specification in 2027 and the new Moto3 machinery due to be introduced in 2028.
