RoadRacingWorld.com has a interesting article (https://www.roadracingworld.com/news/american-flat-track-major-changes-coming-to-the-premier-class-in-2020-with-entry-restricted-to-16-contracted-riders-or-teams/)on a serious change to its flat track racing for 2020.
They have created a "SuperTwins" class.There will be only 16 teams in this class.Each team must enter all races for the year 2020.
AMA has done many shocking things since I started racing. Some worked out very well. Others made me shake my head and say :wtf:
