MotoAmerica announced its new racing class structure for the newly-christened 2015 AMA/FIM North American Motorcycle Road Racing Championship. MotoAmerica’s inaugural season will feature four classes headlined by the Superbike class, with discussions for an additional two classes.

Joining the Superbike category will be the 600cc-class Supersport (formerly known as Daytona Sportbike), Superstock 600 (formerly known as AMA Pro SuperSport) and the Superstock 1000 class. MotoAmerica is still putting together its rulebook but did provide an outline at how the new class structure will mesh with the old classes and the FIM’s international racing series.

“The 2015 MotoAmerica racing classes were designed to be more performance oriented and in line with FIM international road racing classes,” says MotoAmerica partner Chuck Aksland. “These new racing classes were created in collaboration with the AMA, FIM, and with input from key industry teams and partners. We are excited and looking forward to the 2015 MotoAmerica Motorcycle Road Racing Championship season.”

The Superbike class will retain the previous AMA series’ chassis rules. Teams will still be able to use their 2014 season gearboxes, but superbike engines will be brought in line with the 2015 World Superbike Championship‘s specifications, which includes three- and four-cylinder engines displacing 750cc-1000cc and Twins displacing 850cc-1200cc.

Teams will also be able to use their 2014 electronics for one more season, but otherwise they must comply with WSBK‘s electronics regulations. Presumably, this means a price cap on ECU kits while factory teams must make the programming available for other teams to use. Riders will be allowed the use of two superbikes per race event.

The new Superstock 1000 class will race along with Superbikes but will be scored separately. Engine and chassis specifications will align with the FIM’s Superstock 1000 regulations. Teams will be allowed to modify the brake system and run on slick tires. As with the Superbike class, riders will be allowed two bikes per event.

Supersport machines will follow 2014 AMA-spec chassis rules while engine regulations will be closer in line with World Supersport rules, allowing 600cc machines and 675cc Triples. Supersport machines will be allowed to use electronics from 2014 AMA regulations and slick tires. Unlike the literbike classes, Supersport riders will only be allowed one motorcycle per event; teams will be allowed to have a second, but will not be able to use them without approval from the Technical Director.


The Superstock 600 regulations will be similar to the previous AMA Pro SuperSport’s rules and aligned with FIM Superstock 600 rules.

MotoAmerica is currently in discussions to run two additional classes. No details were provided, but possibilities include a beginner-class spec series, Twins or a Formula USA-style Open class. The only thing ruled out is a Moto2 class, though MotoAmerica says it will re-evaluate that class for the 2016 season.
