Classes

Motocross Classes are grouped by 
Age – Minimum age as of the riders birthday, Maximum age as of Dec 31st.
Bike size - Motor size and/or wheel size. 
Skill -  Based on the ”Riders” riding abilitity and speed.

Skill classes are grouped by  Novice, Intermediate and Expert
Depending on the size of the “Skill Class”, it may be further divided into sub-levels “A” and “B”.  “A” being faster then “B”.   Only the “A” class will accumulate series points.  “B” classes still win race day awards such as trophies.  Riders can move up the sub-levels as there skill level improves.
Sub-level Example: Novice “A” and  Novice “B”

CMA Licenses are issued based on the riders age at the time of application.   Maximum age is based on the age of the rider AT THE END of the license year.  With proof of age, riders can move to the next age class on or after their birthday within the license year, but they must contact CMA to adjust their license classification.  A CMA License representative is available at all race events.
