Riders who do not go onto the grid may start the warm-up lap from the pit lane under the instructions of a marshal positioned at the pit lane exit. Such riders must have tyre warmers removed and may not change wheels after the display of the 3 minutes board. Riders starting the warm-up lap from the pit lane must start the race from the back of the grid. If there are two or more riders starting from the back of the grid, they will take up position in the order in which they qualified for the race.

The names of the teams will be composed of three elements: the name of the manufacturer of the motorcycle or engine (mandatory), the name of the team (mandatory except when the team name is the same as the manufacturer) and the name of the main sponsor (optional). All points scored by both riders in the team, including substitutes or replacements, will count toward the Team Championship; in the case of a one rider team, only the points scored by that rider will count. Wild card riders do not score points.

-Entries; a rider shall be deemed to have taken part in the event when he participates in, at least, one practice session. A rider shall be deemed to have started a race when he participates in, at least, the first lap of the race.
