Aprilia:

* A 'withdrawn' engine means it is no longer available, usually because it has either reached the end of its lifespan or suffered some kind of damage.

**Quartararo's lower-spec M1 package is thought to mean he has only 5 engine changes planned for the season, instead of the full 7 allowed, resulting in a lower rpm limit to extend engine life.
