MotoAmerica Announces Class Structure

Costa Mesa, Calif. (October 3, 2014) – MotoAmerica has announced the primary racing class structure for the 2015 MotoAmerica AMA/FIM North American Motorcycle Road Racing Championship season.

The premier class for the MotoAmerica Championship will be the Superbike class. The Superbike class will feature a rules package based on a combination of current AMA Superbike chassis and 2015 World Superbike Championship engine specifications.  Racing alongside the Superbikes (but scored separately) will be the Superstock 1000 class. The Superstock 1000 class will be closely aligned to FIM Superstock 1000 rules, run on slick tires, and help to provide an action-packed race for MotoAmerica fans.

Sounding a lot like WSBK and their EVO class I am never a fan of multi class racing just to enlarge the field. The only place this works is in endurance racing where the relative strengths of the machines can be balanced out. Coverage of these secondary classes in the main race is so sparse it is hard to care.

Middleweight road racing is one of the most exciting classes of racing worldwide. The primary MotoAmerica middleweight road racing class will be the Supersport class (formerly AMA Daytona Sportbike). The MotoAmerica Supersport rules have been designed to utilize 2014 AMA chassis rules, run on slick tires, and have engine rules aimed at moving toward FIM World Supersport Championship specifications. In addition to the Supersport class, MotoAmerica will also rename the current AMA Pro SuperSport class to be Superstock 600.  The Superstock 600 class rules will be based on 2014 AMA Pro SuperSport rules and be closely aligned with FIM Superstock 600 regulations.

This will probably be the most exciting class with bar to bar battles and young riders who have either not developed common sense, or fear.

MotoAmerica is also currently in discussions for two additional racing classes in the MotoAmerica Championship and will be announcing that information as it becomes available. The MotoAmerica full technical rules will be released shortly.

I really hope one of these is the XR1200 series. Not a technical series, nothing flashy, but wow some great racing!

“The 2015 MotoAmerica racing classes were designed to be more performance oriented and in line with FIM international road racing classes,” MotoAmerica partner Chuck Aksland said. “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.”
