RIDER / PARTICIPANT INFORMATION
713 Racing Promotions uses AMA age guidelines. Your age classification is your age on January 1. The exception is in the Vet Open classes (30+ and 40+), in which the rider must be 30 or 40 years old or older on the date of the race.
All riders 12 years old and younger should bring a copy of their birth certificate or proof of age prior to participating in their first race.
All riders under the age of 18 and the minor rider’s parent or legal guardian must sign the Parental Consent, Release, and Waiver of Liability, Assumption of Risk and Indemnity Agreement prior to participating in the Event.
All riders receiving a payback award must complete and sign a W-9 form before receiving payment.
SAFETY & PROTECTIVE GEAR
Full-faced helmets must always be worn whether warming up, practicing for competition, or while engaged in the competition. Shatterproof goggles or eye protection is also required. Sturdy, protective boots must be worn and must cover the ankle. No rubber boots or tennis shoes will be allowed. Motocross pants, gloves, long sleeved shirts, and chest protectors are strongly recommended. Knee protection is also strongly recommended.
Kickstands must be removed. Bikes are required to be off-road motocross dirt bikes, no dual-purpose models, headlights, turn signals, or brake lights are allowed.
BIKE / NUMBER INFORMATION
All bikes must have three number plates attached to the bike, one on the front and one on each side. Number plates should have numbers only, no letters. Numbers are strongly recommended (READ THAT AS REQUIRED) to be black on white background, black on yellow, or white on black. Numbers must be highly visible so they can be seen easily by the scorekeepers. If the scorekeepers cannot see the number, the rider will not be scored.
If two or more riders in the same class choose the same number, the first rider to preregister or register with that number shall be allowed to use it and subsequent riders must select an alternative number or run an “X” over their current number. A rider will be notified of the requirement to change his/her number as soon as a duplicate number is identified, which may be up to the start of heat races.
