The following provisional 2005 MX1/MX2 calendar has been proposed by Youthstream, rights holders to the Motocross world championships, to the FIM.

The calendar again contains 16 events, but among the proposed changes is the inclusion of new events in Japan and England, while the Benelux and Wallonie GPs have been dropped. The 2005 Motocross des Nations will be held in France.

The calendar remains provisional until ratified at the FIM congress in October.
