Dorna has announced that the Dutch round of ꧃t🐷he 2021 World Superbike Championship, scheduled for Assen in April, has been postponed until July 23-25.

The date change has been req𝄹uired due to the latest Covid-19 🧸restrictions, with local authorities determining 'no major events may be held in Drenthe until the 1st of June 2021'.

Assen - which&nbꦰsp;was one of seven WorldSBK events cancelled due to Covid last season - thus slots in as round five on the provisional 2021 calendar, just before the summer break.

'FIM and Dorna WSBK Organisation are constantly working with Government Officials and Circuits in order to contiဣnue putting the safety of everyone first. Any further updates to the 2021 WorldSBK calendar will be communicated accordingly,' said a statement accompanying the Assen move.

The neꦰw season is ꩵdue to start at Estoril in early May and conclude with Indonesia in mid-November, although it remains to be seen if any of the non-European rounds will be possible this year due to Covid restrictions.

The⭕ new Mandalika circuit also remains 'Subject to Homologation', while Phillip Island (which was the only non-European round of 2020, taking place before Covid restrictions) is cꦛurrently 'Subject to Contract' and lacking a date.

One place on the provisional 2021 calendar remains reserved ♏for a 'To Be Announced' event.

The World Supersport Championship is due to attend all of the rounds listed with the exception of Donington Park. The WorldSSP300 class is pencilled in for al🐭l European events, also with the exception of the UK.

An official pre-season test will be held at the Circuit de Catalun🥂ya-Barcelona on March 29-30 for WorldSSP and WorldSSP300, before WorldSBK takes over at the Spanish track on March 31-April 1.
