Everts was called up to represent Belgium at the 2021 Motocross des Nations for the first, helping his country finish sixth overall and fourth in the MX2 class as an individual.

[7] He moved full time to the MX2 class during the 2022 FIM Motocross World Championship, signing for the Diga Procross KTM team.

An eventual tenth overall in the final standings caused Everts to make his second appearance for Belgium in the 2022 Motocross des Nations.

By round ten in Germany, Everts was able to seize on a mechanical issue for Lucas Coenen to win the second race and by extension the Grand Prix.

This placed him second with two rounds to go, but, a heavy crash in the same race that his teammate Andrea Adamo became world champion meant Everts would ultimately drop to fourth in the final standings.

He missed the opening round of the 2024 FIM Motocross World Championship due to a right thumb injury sustained pre-season.

He scored three more podiums throughout the rest of the season but a crash with Lucas Coenen at the penultimate round in China saw him sustain a broken C5 vertebra which ended his campaign.
