The runner-up position remained up for grabs in Valencia, as four-time winner Thomas Lüthi, double winner Álex Rins and Franco Morbidelli all had a mathematical chance of finishing there. Ultimately with a second-place finish, Lüthi finished clear of Rins by 20 points; Lüthi's last-lap pass on Morbidelli also cost the latter third place in the championship by a point, as Rins had finished the race in fifth place. Morbidelli took a total of eight podium finishes, including each of the last five races, but was unable to take a victory. Four other riders won races; Sam Lowes took two race victories at Jerez and Aragon, Jonas Folger won at Brno, while first Grand Prix victories went to Takaaki Nakagami at Assen, and Lorenzo Baldassarri in Misano. The constructors' championship went to Kalex with a maximum score of 450 points, with a 34-race winning streak at the conclusion of the season – a run stretching back to a Speed Up victory for Lowes at the 2015 Motorcycle Grand Prix of the Americas.
