I believe they do not help League Speedway though. Personally I rue the day that they ever got involved in Speedway. They have screwed Speedway in more ways than one - taking Money out of the Sport. If, as Philip says the Riders get more from Sponsorship - it is just as well. Apparently the Riders are paid buttons by BSI. I don't know how much BSI pay the Riders - but - I have heard that it isn't a lot. If this is true - SHAME ON THEM!!
It is the RIDERS who are putting their necks on the line - they should get a decent amount from the Owners of the GP Series.
