Rumors running through the motorcycle industry are that DMG will adopt FIM World Superbike rules for the headlining class at DMG-promoted, AMA and FIM-sanctioned Superbike Nationals starting in 2009. According to a racetrack executive who said he wished to remain anonymous because he was not authorized to discuss DMG’s latest plans, the Factory Superbike class will not run spec tires, spec fuel, spec electronics or any other restrictions, and factory teams will be free to test as much as they wish. There will be no minimum or maximum participation requirements imposed on the brands participating in the class, the track source said. In the past the track source has proven reliable. Reached by phone at his Florida headquarters, DMG’s Roger Edmondson said he had no specific comment, but then said, “We are working on finalizing our plans but are not ready to announce what we’re doing.”
