Earlier this month, the AMA and MotoAmerica released a preliminary set of rules for the various classes in the 2015 roadracing season (then later, announced some tweaks to the rules). The classes and rule structure were designed to more closely resemble the rules outlined in other national series and the World Superbike championship. The rules have yet to outline what is and is not allowed in the KTM RC390 Cup, but is otherwise a relatively complete set of guidelines for teams to get started with their 2015 preparations.
However, as with any rulebook, there’s a lot of technical jargon to sort through. Here to condense the rules into an approximately five minute explanation is Greg White. In this video, provided by the American Motorcyclist Association, White gives a quick run down of each class, and why the new rules package should benefit the future of American roadracing.
