Enea Bastianini and Albert Arenas clinched the world championship title in Moto2 and Moto3 category respectively after a dramatic finale in both classes.

Several Grands Prix were cancelled or postponed after the opening round in Qatar was halted, prompting the Fédération Internationale de Motocyclisme to draft a new calendar.

The Portuguese Grand Prix, absent from the calendar since 2012 (when it took place at the Autódromo do Estoril), was introduced as the last stage of the championship; this is the first time the season finale has not been held in Valencia since 2001.

After having achieved the arithmetic certainty of winning the World Championship, Joan Mir leads the riders' standings with 171 points, 29 more than Franco Morbidelli who won the previous Grand Prix and gained three positions in the general classification.

In the combined standings, the new world champion Joan Mir and the winner of the previous race Franco Morbidelli remain excluded from Q2.

[6] In the combined free practice times table, Remy Gardner was the fastest ahead of Luca Marini and Héctor Garzó.

Among the contenders for the bikers' title, Ai Ogura beats Q1 and in Q2 qualifies fifth ahead of Albert Arenas, while Tony Arbolino does not exceed Q1 (thirteenth time) and finishes in twenty-seventh place.
