Sorry I did not get back with you sooner, I had a note to ask Mike this question and I did not follow up on till your new request. We will add the D-first year class back in. I checked last year and we averaged 9.4 riders in this class. The AMA does not recognize a D-class for points so this will be an MAXC points class only. To receive AMA points a rider must run in a C-class or above. Thanks for your patience!
