The AMA and MotoAmerica, the new home of the AMA Superbike Series, have announced updates to the rulebook for MotoAmerica, an AMA national championship series and an FIM North America championship. The changes include adding weight to motorcycles in the Superstock 1000 class and a change to the spare-motorcycle requirement in the Supersport class.
To match the recently released FIM Superstock rules, motorcycles competing in the Superstock 1000 class must now weigh a minimum of 170 kilograms (374 pounds) — up from the previously announced weight of 168 kilograms (369.6 pounds). Additionally, motorcycles competing in Supersport and Superstock 600 must comply with a new lowered Superstock Kit ECU price cap of Euro 2,500.
The AMA has also made a change to its spare-motorcycle requirement in the Supersport class with riders and teams now permitted to use their backup motorcycles in the warm-up sessions. Previously, the spare motorcycle could not be used in any practice/warm-up sessions. Teams and riders must, however, declare their primary and spare motorcycles during the initial tech inspection and prior to any on-track activities.
Additionally, the AMA has created an Annex A to all classes, which is basically a rule-change list. Teams and riders can now refer to the Annex A list to more easily track rule changes.
The AMA will also publish approved equipment lists and requirements for suspension and electronics. There will be no fees associated with the application to include components to the approved equipment lists; and there will be no approved equipment lists other than the aforementioned suspension and electronics lists.
