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.
