- AMA Formula Xtreme
Formula Xtreme is a professional racing class that is sanctioned by the
American Motorcyclist Association , the premier (largest and most widely covered by media) motorcycle racing sanctioning body in the United States. Formula Xtreme is part of the AMA's Superbike Series, which also includesAMA Superbike Championship ,AMA Supersport Championship , andAMA Superstock .In order to be successfully entered in a Formula Xtreme event, motorcycles must be
homologated . They must also be of a model type that is designed and legal for street use in the United States and is available from retail dealerships in the U.S.Although liberal by the standards of the other classes in the AMA Superbike Series, Formula Xtreme rules still limit the modifications that may be made to a motorcycle to be entered in a Formula Xtreme event. The rules specify what changes are and are not permitted, including modification or replacement of various engine internals, transmission components, and other non-powertrain components of the vehicle such as the suspension, wheels, frame, swingarm, bodywork, wheels, etc. The rules also specify mimimum weight limits, allowable fuel types, which production components must be left in place and rules for availability of non-stock components from the manufacturer. Lastly, the type of engine (displacement and configuration) is governed by a set of guidelines that attempts to bring technical diversity to the class by establishing technical limitations that allow different technologies to remain competitive. For example, air/oil-cooled twin-cylinder engines are allowed a larger displacement limit. There are also differences in allowed modifications to engine internals depending on the engine configuration, again to encourage technical diversity in the class by ensuring that motorcycles with different engine configurations remain competitive.
