The 2017 FIM Moto2 World Championship was a part of the 69th F.I.M. Road Racing World Championship season.
The season was marred by the death of Stefan Kiefer, head of Kiefer Racing, in Malaysia. Johann Zarco was the reigning two-time series champion but he did not further defend his title as he joined the series' premier class, MotoGP.
The 2017 season was the first season for the KTM Moto2 chassis, after KTM expanded its factory operations to Moto2 and MotoGP.
