" OD: The Daytona SportBike class is designed to allow the participation of a variety of two, three and four-cylinder machines of different designs. This eclectic assembly of motorcycles is consistent with the makeup of the class (which ran in past years under the name of Formula Xtreme, which allowed for machines ranging from 550cc four-valve, liquid cooled, four cylinder bikes to 1350cc two-valve, twin cylinder air cooled bikes). Daytona SportBike allows for a similar mix of equipment that is based on weight and performance characteristics that allow for balanced competition among a large and varying range of motorcycle designs.

This still does not answer the question why Buell's 1125 Water Cooled Rotax Twin Engine (making almost 140hp stock) is in this class, he basically dodged the question, notice he did not go into specific dyno numbers as well, I would love to know what the Race version of that bike is putting to the ground vs the 600's.
