C. Administer and keep track of points from all events sanctioned, and publish annual and semi-annual points standings.

D. Provide for qualified riders, year-end awards for the top three or 33% (which ever is the least amount, signed up in their classes for the year. However, more awards may be given out if the SIDRA race committee has funds available.

E. Maintain a racing program that will continue to encourage new riders.

F. Continue to try to achieve safe standards for course layout and marking.



The SIDRA race schedule will run from Jan. 1 to Dec. 31.

1. All SIDRA sanctioned events should be two weeks apart.

2. No SIDRA rider can be made to race more than one day every two weeks for points.  SIDRA can grant a waiver for this rule in extenuating circumstances. 

3. On any dual sanctioned or multiple day event, the SIDRA day to receive points is preferred to be the first day, to eliminate pre-riding of the course. (This can be waived if voted on by the SIDRA race committee prior to the race).

4. Minimum time for cancellation of an event is twenty-one days prior to race date, unless information leading to the cancellation from outside sources is received in less than the required time limit. 

5. If a club cancels their race, it is their direct responsibility to make sure all SIDRA members are informed prior to the event date.

6. To receive points and qualify for year-end awards, every rider must have a SIDRA membership card.

7. All members must have an AMA card at all AMA events.

8. All riders must have the correct color number on the correct color background for the division they are entered in, (on all three number plates) or they can be disqualified.

9. Pre-entry on timed events cannot open until 3 days after the flyer postmark.



a. All starts will be "Dead Engine" with the rider sitting on the seat. Gran Prix races can be excluded from this rule.

b. A banner or large flag must be used to start all races. (When the banner is raised, all engines must be shut off. When the banner is dropped, the race is started).

c. In the event there is an issue with the race starting after the starting banner has been raised, a red flag will be used to signify that the race will not start. The red flag will be used as a visual communication between the starting line and the starting banner and also a visual communication to the racers that the start of the race has been stopped.

d. In the event of a check being ruled unofficial, the promoting club will give tentative results to the riders, will hold the trophies and take no more than one week to determine the best and fairest method of scoring. 

Promoter will then provide determination to Sidra within that week.    

e. All sponsor clubs will have verbal and visual communication between the starting line and where the starting banner is being dropped. 

2. There must be a clearly defined start line between two definite points. (Stakes, etc.)

3. The sponsor club, at their discretion, shall start the A classes first, B second, Women and C last. A single or multiple wave start may be used if there is enough room to incorporate it safely.

4. No roads can be used to traverse the area between the start area and the trailhead, no matter how old the road is. When ever possible, every club will incorporate into their start area a return course for safety sake, and it should be marked with a different color than the regular course markings.

5. For safety sake, mini bikes are never allowed on the big bike course at the same time the big bikes are racing. The mini bikes can however, ride on the big bike course either before or after the big bike race.

6. All events must stipulate a definite finish line and must have a checkered flag to signify the end of the race.

8. Whenever possible, home check should be separate from the finish line for safety reasons.

    1. If the event is a dual sanctioned event, i.e. AMA Hare and Hound, then it is acceptable to combine classes where a direct mapping makes sense.

2. All protests must be given to the promoting club’s SIDRA rep in charge of the race. This can be done only by a member of the promoting club, or by a rider that participated in the event. No protests will be accepted from any other outside source. All protests must be filed within 30 minutes after the last rider finishes the event. All protests will require a $20.00 deposit at the time of the protest. If the protest is not upheld the promoting club will keep the money. Harassment of the referee may negate reimbursement.

3. All mechanical protests will require a $100.00 deposit and will be performed at a competent dealer shop of representative’s choice. If the protest is upheld the money will be refunded to the person that filed the protest. In such a case the protested party will have to pay the bill to get the bike back.

      1. If the transponder is lost, a rider can still be considered a finisher if the lost transponder is paid for ($20). 
    2. The rider is also responsible for carrying the transponder appropriately to ensure it will be read by the electronic system. If the transponder does not read the rider may be asked to stop and make adjustments to correct the issue. (The units are extremely reliable if carried appropriately.)

B. Team races do not count as transfer rides.

C. If you place high in overall finishes of different races you will be reviewed to be moved up.

Main course – shall be marked in pink or orange tape. Arrows and signs may also be used.

Turns – shall be marked with yellow tape on the side of the trail in the direction the course is going to take. (If the tape is on the right side of the trail, the course is going to turn right, and visa versa.)

Danger Areas – shall be marked with blue tape and/or X’s on pie plates or arrows pointed down at least one hundred fifty feet before the danger area. Extra dangerous areas need to have more marking than small danger areas do. Danger areas that must be marked are drop-offs, ditches, roads, rocky areas, sharp curves, and any other thing that could pose a life-threatening problem for the racer.

1. In open terrain, each piece of flagging should be visible from the previous piece of flagging.

2. In gullies with high sides, sand washes, and roads where course is obvious, the flagging does not have to be any closer than 200 yards apart.

3. When a race course crosses a road there must be an adequate amount of marking on the other side of the road so that riders do not get lost. All road crossing must be marked as such.

4. Riders must understand that in all cases cars have the right of way.

5. All road crossing with traffic must have flagmen. All riders must understand that in most cases any road crossing with a flagman requires that you stop, get off your bike, and walk your bike across the road.

6. Check points must be clearly marked and visible to the riders for at least 150 feet before they must stop. Secret checks designed to cut down on cheating may waive this rule.


7. Electronic scoring will be maintained for a minimum of 2 hours after the winner crosses the finish or until all riders are in and accounted for, whichever is shorter. After the 2 hour cutoff the electronic system may be brought down at the discretion of the race referee and scoring personnel so results can be calculated and distributed in a timely manner for the majority of participants. Riders may still finish and earn series points after the cutoff but their finish time and sequence will be entered manually and published online with final results
