Rule changes
This class and Moto2 adopted the qualifying format used by MotoGP for the season, in which the riders that placed 15th or lower on combined times in the third free practice session would be admitted to qualifying 1, then the four fastest riders from that session would join the fastest 14 riders in qualifying 2.

The season saw the introduction of a new penalty called the "Long Lap" penalty for infractions such as exceeding track limits or engaging in reckless riding. At each circuit, a route is to be defined and marked at a safe point around the circuit (usually an asphalt run-off area outside of a turn). The penalised rider must ride through the defined area within 3 laps of being notified, thereby suffering a penalty equivalent typically to 2 or more seconds on that lap.

Calendar
The following Grands Prix took place during the season:

Riders' standings

 * Scoring system
