As expected the start of the Dutch Masters of Motocross 2021, set to start at the end of March and be some pre-season racing for the GP riders has been postponed. The first two rounds of the series in Harfsen and Oss won't go ahead on the 21st and 28th of March due to the corona pandemic still having a major effect on the people of Holland, and restrictions being updated by the week. 

The KNMV is looking for new dates for these venues later in the season. Remaining rounds in Oldebroek on the 17th of April, Arnhem on the 2nd of May and Rhenen on 5 June seem likel to remain on those dates.
