Scott Hollingsworth, AMA Pro Racing CEO said that these proposed rules have been developed as a direct result of input made by the advisory boards of each racing series. ¿With the valuable contributions made in part by our advisory board members we have produced refinements and improvements to the technical rules for each of our disciplines,¿ said Hollingsworth. ¿The next step in this important process is to open up the proposed rules to our 30-day comment period. We expect to receive additional insight that will be considered before final rules are sent to the AMA Pro Racing Board of Directors for approval.¿
