AMA Pro Racing fields two production-based SuperSport classes, 600cc and 750cc, based on the maximum displacement of their engines. Twin-cylinder machines with less than four valves per cylinder are allowed to make engine modifications. All other engine configurations must remain in stock condition, as they are originally supplied by the manufacturer.

While SuperSport motorcycles have a similar outward appearance to the Superbikes, rules severely restrict allowable modifications. Primarily, carburetor jetting and approved aftermarket exhaust systems are allowed. These bikes retain much more of their standard--but nevertheless impressive--power and handling characteristics.

Because most of the differences between SuperSport and Superbike are internal, the most visible difference is that SuperSport bikes use DOT-approved street tires, instead of the racing slicks used in Superbike competition.

Qualifying procedure:
For timed qualifying events in Superbike and classes requiring an Expert license, a rider's best lap time must be within 115% of the fastest qualifying rider's best lap time in order to pre-qualify for one of the available grid positions in the final race. Riders in the top-10 in points of a particular class, currently or at the end of the previous season, will be permitted a total of one provisional start per season in that class. Provided the grid is not full, this will allow such riders to be placed on the back row of the grid should they not qualify through the normal procedure. Riders will not be permitted provisional starts in more than one class in a season.

Both final AMA SuperSport races are 60 kilometers in length.
