American Retrocross Class Structure

Our philosophy is to give every rider the opportunity to race two classes with the same bike. See where you and your machine fit in and keep in mind that there is a Novice, Intermediate and Expert category for each class.

Race Rules

We have enough rules to create a level playing field and no more.

  • 1.) Sign up closes at 8:45am SHARP. No exceptions, so please don’t ask.
  • 2.) Rider’s meeting is at 8:45am and is mandatory. No refunds after rider’s meeting.
  • 3.) Practice begins at 9:00am and is segregated into bike categories to create a safer mix of machines. Only ride your category.
  • 4.) An ARX official will lead the first lap of practice to assure everyone is clear on the layout. Do not pass the lead rider on the first lap.
  • 5.) If you do not ride practice you cannot race. Simply too dangerous.
  • 6.) Pit speed is 5 mph and you must wear a helmet.
  • 7.) ARX is all about friendly racing. Aggressive riding will not be tolerated.
  • 8.) Riding in a class you are not signed up for or allowing someone to ride in a class they are not signed up for will result in disqualification.
  • 9.) Kick stands must be removed before practice.
  • 10.) Have contrasting numbers on all three number plates.

Nope but membership has its privileges, like: discounts on entry fees, year end awards and a positive impact on your IQ and FICO scores!

Yes, typically but it is always wise to call the track and verify if camping is available and what time they close the gates.

Sign up opens at 7:30 and closes promptly at 8:45. Rider’s meeting at 8:45. Practice begins at 9:00. First race at 10:00. Day is done at 1:00

You can find lots of them on our Facebook page HERE and on our Instagram page HERE

Nope but there is a rule page. We don’t think that racing at this level needs any more than that. Click here: https://americanretrocross.org/rules-and-class-structure/

Not after the riders meeting is concluded. We have no control over your bike prep or physical issues.

No sorry. This is a Vintage to Vet racing club and we cater to that age group. There are lots of great racing organizations that cater to kids and small bikes.

Minimum of 5 events to qualify for year end awards but you have to be a member for all 5. Membership will not give you retroactive points.
