I’m not sure the ‘ rights holder ‘ is that involved once they have put everything in place pre- season.
The meeting promoters along with the FIM control all aspects from practice/ qualifying to the meeting proper- ie Jury president, race director, clerk of the course etc etc.
TV It seems like the revised contract doesn’t involve the TV side of it which means WBD have that responsibility.
As Mayfield won’t be promoting any of the rounds themselves i don’t see it being a major problem and my opinion is we won’t have less than 10 rounds in 2026.
