The FIM has released an updated version of the 2012 World Superbike and Supersport calendar.

Compared with the pervious version released in September, the latest line-up features 14 rather than 15 rounds, with all events now identified.

The missing event was a TBA announced round on March 4, widely rumoured to have been planned for the Sepang circuit in Malaysia. That will not happen and the second round will instead be held at Imola in Italy on April 1.

Imola, moved forwards from its traditional home towards the end of the season, had not been present on the previous calendar.

Other events remain unchanged, except that the order of the final rounds at Magny-Cours and Portimao has now been switched.

The Portuguese round has been moved forwards to September, meaning the championship will end in France on October 7th.
