ACR Classes, Rules and Race Order
Heavy on fun, light on rules..........
UNDER CONSTRUCTION - for CLASSES - SEE HOME PAGE
ACR has a class for your vintage motocross bike.  We have classes for Pre-75 bikes all the way through to Modern machines!  Some are divided up by skill, some by age, and some by era.  Check out the classes below for full descriptions. 

THIS CLASSES LIST IS NOT A RACE ORDER- FINAL RACE ORDERS ARE DETERMINED AT THE TRACK
RULES
ACR has always been focused on the fun factor of Vintage Motocross racing.  As such, the rules are few.  ACR has a family atmosphere and everyone expects that you conduct yourself in a manner that would make your mother proud.  Below is the short list of rules.  The ACR team is always open to suggestions and feeback.
1.   The minimum age for all classes is 16 years except for the Greenhorn Class and the Youth Mini (8 & up).
       This may vary due to individual state laws so check before you haul!
2.   All Pre-75 machines must have no more than 7 inches of front wheel travel and 4 inches of rear wheel travel.
3.   Pick a number and stick with it for the entire season. New riders should check to be sure their desired number isn't already in use.
4.   If the results are wrong at the track, get them fixed at the track. Make sure they are fixed before you leave.
       It may not be possible  to adjust the scoring later.
5.   To qualify for individual year end awards you must participate in a minimum of 5 events in the same class.
 



What's my skill level?

•ACR believes in the honor system. You know how fast you are. If you are an expert on your modern bike and are getting into vintage motocross, then you should sign up for the expert class for vintage racing as well. If you were a novice level rider when you hung up your boots 20 years ago, sign up for the novice class. If you blow everybody away in the skill level you signed up for, move up. Sandbagging is just poor form.
