01.01 INTRODUCTION The term motorcycle covers all vehicles having, in principle, less than four wheels, propelled by an engine and designed essentially for the carriage of one or more persons of which one is the rider of the vehicle. The wheels must normally be in contact with the ground except momentarily or in certain exceptional circumstances. Furthermore, in order to traverse certain surfaces one or all of the wheels can be replaced with skis, rollers or chains. 01.03 FREEDOM OF CONSTRUCTION A motorcycle must conform to the requirements of the <strong>FIM</strong> regulations, to the Supplementary Regulations, as well as to a number of specific conditions that the <strong>FIM</strong> may require for certain competitions. No restriction is placed on the make, construction or type of motorcycle used. All solo motorcycles (Group A) must be constructed in such a way that they are entirely controlled by a rider. Motorcycles with Sidecars (Group B) must be constructed to carry a passenger. 01.05 CATEGORIES AND GROUPS OF MOTORCYCLES Motorcycles are divided into categories which must be observed for all meetings and world record attempts. In principle, it is forbidden for different categories, groups and classes to compete in the same race, unless the Supplementary Regulations state otherwise. Category I Motorcycles propelled by the action of one wheel in contact with the ground. Category II (not applicable for Track Racing) Special vehicles propelled by the action of one or more wheels in contact with the ground but which are not covered by the conditions of Category I. Group A1 - Solo Motorcycles 2-wheel vehicles making only one track on the ground. 3 General(e) Section
