The 2018 MXGP World Championship will span the full 20-round schedule as Bulgaria has been added to the revised calendar.

Sevlievo will return to the series on 26 August for the first time since 2014, effectively taking the place of the cancelled Swedish GP.

In 2014 it was Red Bull KTM’s Antonio Cairoli who took the premier class overall after trading moto wins with Gautier Paulin, while in the MX2 ranks there was no denying Jeffrey Herlings the double for the weekend.
