Rider/Participant Information

The rider’s age as of October 1, 2017 is the age the rider should use to determine age-based class qualification with the exception of the Vet Open class, in which the rider must be 30 years old or older on the date of the race.

All riders 12 years old and younger must present a copy of their birth certificate or proof of age prior to participating in their first race.  If riders have previously provided proof of age to 4Gmx, they do not need to provide it again.

All riders under the age of 18 and the minor rider’s parent or legal guardian must sign he 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 and Protective Gear

Full-faced helmets must be worn at all times whether warming up, practicing for competition or while engaged in 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, full-length sleeved shirts and chest protector are strongly recommended.

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 must 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.

In the event that two or more riders in the same class choose the same number, the first rider to preregister or register with that number shall be allowedto use it and subsequent riders must select an alternative 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.

Event Information

Gate position for the heat races will be determined by random order.  Gate position for the main event is determined by the finish order of heat races and LCQ’s.

Number of laps for practice, heat races, LCQ’s and main event will be determined by the promoter and rides will be notified of this and race order during the riders meeting.

A rider will be moved to another class if a track official or the promoter determines that the rider’s ability is not appropriate for the class in which he/she registered.

Riders are expected to be courteous of each other and of track personnel at all times.  All riders are responsible for their own conduct as well as all pit crew.  Emotions tend to run high in competitive events, and riders are reminded to behave with sportsmanlike conduct at all times.

Riders who do not follow track rules will be disqualified.  Reasons for disqualification may include but are not limited to:

  • Violent behavior toward or cursing at any official
  • Distraction or interruption of the scorekeepers at any time
  • Interference with any race official, medical or track personnel
  • Unsportsmanlike conduct or abuse of another rider/participant
  • Inobservance of official flags
  • Use of drugs or alcoholic beverages prior to or during an event by the competitor and/or pit crew on the premises
  • Riding under another rider’s name or number


Disagreements with finish placements must be brought to the attention of the promoter before trophies have been awarded.

Protests, whether of rider, machine or rule violations, must be clearly written and presented to the promoter accompanied by a fee of $50 within 30 minutes after completion of the last race of the evening.  IF the protest is found valid, the fee will be returned.  If the protest is not valid, the fee will be forfeited to the person or track being protested.  An official may post without any fee.
