Bike aces are facing a longer wait to get back on track.
The British Superbike Championship and support series calendar has been rescheduled in a bid to let more spectators attend the races.
With this in mind the championship - celebrating its 25th anniversary in 2021 - has pushed its calendar back a number of weeks.
A BSB statement read: "Promoters MSVR has been in talks with the Department for Digital, Culture, Media & Sport (DCMS) over recent weeks to clarify aspects of the government’s roadmap plan - in particular the capacity limits that apply to non-seated venues during step three (May 17-June 20).
"With no further information available, and the need to offer certainty to fans, series partners and stakeholders, the calendar has been updated and all events will now take place beyond June 21 – the date which provisionally marks the easing of spectator restrictions at large elite sporting events.
"Consequently the opening round of the 2021 Bennetts British Superbike Championship will now take place on June 25-27 at Oulton Park, around a month later than previously planned."
Events at Thruxton and Snetterton, which were set to take place prior to June 21, have now been rescheduled.
The official test programme was due to get underway this weekend. However, the first test will now be held at Silverstone on April 28-29.
Bennetts British Superbike Championship series director Stuart Higgs commented: “Since the government’s roadmap was published in late February, we have been in constant contact with the Department for Digital, Culture, Media and Sport to understand its implications for spectator attendances.
"Unfortunately, the DCMS is still not in a position to confirm what capacities will apply prior to June 21.
“With the start of the season rapidly approaching, and to offer the best possible chance of having all our fans back trackside, we have made decisive changes to the calendar to deliver the best opportunity for this to happen as we look ahead positively to our 25th anniversary year.”
