2009 United States RMC Class Structure:

The class structure for the 2009 United States Rotax Challenge is now set. The requirements for the Micro Max class, introduced in 2008, will remain without changes. For 2009 a new classification for the DD 2 class will introduce the DD 2 Masters. There is no separate class for this classification but DD 2 class members can designate themselves as Masters for recognition.
