I think the banning of Russian riders after the Ukrainian invasion byrussian forces may have had something to do with it.
I may be wrong, I'm sure someone will let me know. π
I don't like the GP System. I believe that, to a point, Speedway lost it's soul following the scrapping of the 'one off' Final.
I loved the 'one off' World Finals though. Excitement, tension, gnawed finger nails right through to the end of the Meeting.
It was great in those days.
