Rules and Regulations

 APPROVED BIKES: SDBA only permits 2-wheel motorcycles with an Internal combustion engine to enter an event. Three or Four wheel vehicles are prohibited from entering a class at SDBA. 

BIKE NUMBERS: See the SDBA "Points System" document to read more about bike numbers. 

BURNDOWNS: If two racers are in the middle of a burndown, the starter will only let them continue for a reasonable amount of time. If any unreasonable amount of time is used the starter will point the racers to go in and stage. If the racers do not go in within 20 seconds of the starter pointing them in, then both racers are subject to disqualification. 

CHANGING BIKES: See policies below for changing bikes in different classes:

E.T.: A racer can change his or her bike in time runs or in 1st round (You still need to notify the tower to change). Whichever bike and rider runs first round it is locked and the bike nor the rider can be changed for the rest of eliminations for any reason. 

Pro: A racer can change his or her bike in qualifying if there is still another qualifying session for the class, however all previous qualifying data will be erased and the racer must re-qualify the new bike (You still need to notify the tower to change). A racer cannot enter a new bike into 1st round or any other round that was not qualified. Rider cannot be changed either. 

CLEAN-UPS & WARNINGS: If you have a problem with your bike such as: not running right, smoking, or excessive tire spin due to leaking fluids. Please pull over and stop as soon as you can safely. This will aid in clean-up time, allowing officials to get the track back up and going as soon as possible. If you are given an official warning, you are subject to disqualification if the starter must check the track behind you a second time. 

DIAL-IN: Always be sure to verify your dial-in is correct on the dial-in board before you start your burnout. Notify a track official if your dial-in needs to be corrected. It is the rider’s responsibility to be sure his/her dial-in is correct. There are no re-runs if you stage to an incorrect dial-in. Once you stage, it is a race. Dial-ins cannot be changed once it has been called to the tower, unless the race is held up and track officials have shut you off. Track officials do the best they can to be sure its correct, but they are only human. No re-runs, credits, or refunds if you stage to the wrong dial-in for any reason. 

GRUDGE RACING: Only the rider whose name is on the tech card may pick up the time slip from the ticket booth. In the event that there is a time slip printer failure and you need to pick up your time slip in the tower, only the rider whose name is on the tech card may pick up the time slip and they must bring their ID to the tower with them. This is done to protect the privacy of your time slip.

LADDERS: Lane choice is determined by the following method when a class is put on a ladder. 

In Heads-Up classes, lane choice is given to the rider with the better qualifying position. 

In Index classes, lane choice is given to the rider with the better qualifying position. 

LANE BOUNDARY: Any bike touching the center line, touching the wall, or hits a foam block during the measured race will be disqualified. In situations where a rider has a true bye or a broke bye in eliminations he/she is considered the automatic winner once he/she stages under power regardless if the bike touches the center line, touches the wall, or hits a foam block during the measured race. However, the rider will lose lane choice the next round. 

MALICIOUS CHEATING: Any racer caught maliciously cheating can be barred from all SDBA events for up to 1 year, forfeit all season points, and have to pay a $1,000 fine before returning to SDBA. Read the rulebooks and make sure your bike is legal. 

MAXIMUM E.T.: All motorcycles at SDBA running Street E.T. Must have a dial in faster than 12.99. All motorcycles at SDBA running Pro E.T must have a dial in faster than 7.99.

MEMBERSHIPS: SDBA does not require an SDBA Membership or license, however all racers are required to display SDBA decals on both sides of their bike. SDBA decals can be purchased at registration for $5.00 per two decals.  Keep them on your bike so you do not need to purchase them again for that bike. 

MULTIPLE ENTRIES IN SAME CLASS: See policies below for entering multiple times in a class: 

MULTIPLE ENTRIES: A single rider can only enter one bike per class per event. A single rider may use a different bike in the same class at a different event. 

PIT BIKES: Anyone who operates a pit bike, bicycle, golf cart, or anything else with wheels must be at least 16 years old with a valid state driver’s license. Anyone operating a pit bike under age or in an unsafe manner is subject to disqualification without a refund. 

QUALIFYING SHEETS & LADDERS: Always be sure to review the qualifying sheets and ladders, and make sure your bike number, name, hometown, and bike information is correct on the day of the race. 

RAINOUT: SDBA will do everything possible to complete the event in a timely manner. In the event of adverse weather conditions beyond our control, SDBA reserves the right to adjust the event schedule, canceling qualifying sessions, and/or rescheduling the event. Once a bike has made a time pass or a qualifying pass, your entry will not be refunded.

RIDER AGE: All participants must be at least 15 years old with a valid state driver’s license or permit. If you do not have a valid state driver’s license then you must be at least 16 years old with state issued ID card. 

SPONSOR DECALS: A class designation decal featuring the class sponsor will be provided for each class. You will need to display this decal on the front of your bike. If you are running the same bike in multiple classes please put all decals together.

STAGING: A rider must move forward into the stage beam, and cannot back into the stage beam. Any rider backing into the stage beam to set the tree will be disqualified. In order to win a round you must stage your bike under power, even if your opponent is broke and unable to stage. If for some reason you are held up by a track official such as: cleaning or getting debris from the track, waiting for slow bikes to clear the track, your engine is too hot to race, tires too cold, etc., let an official know immediately. Once you stage, it is a race. Courtesy staging is enforced in all classes. Deep staging is permitted in all classes, but the starter will not hold the tree. 

STAGING BURNDOWN: If two riders are pre-staged and have been warned by the starter to go in and stage the starter or the race director is permitted to step into the stage beam and light the third light to start the timeout clock, which will force the two riders to get into the stage beam and race. If one rider still does not stage and receives a red-light then he is the loser. If neither rider stages they will both receive a red-light, at this point both riders are disqualified. 

STAGING LANES: During eliminations, ET classes will be chipped in the staging lanes and the bye run will be based on the quickest reaction time from the previous round or time trial. All pro classes will be laddered for eliminations. Once bikes are paired on a ladder, all broke bye runs must wait until all pairs have been run first before you will be allowed to make a broke bye run. This effort gives the bike racers, that are not in the lanes yet a chance to make it to the lanes before the last pair of bikes makes it down the track. If this rule is taken advantage of by a particular team on a common occurrence, then the race director will decide what action will be taken. 

STARTING LINE AND STARTING BREAKAGE: If for some reason you are held up by a track official, such as to change a wrong dial-in, cleaning or getting debris from the track, waiting for slow bikes to turn off of the shutdown area, etc., and your engine is too hot to race, or tires to cold, let an official know immediately. Once you stage, it is a race. All bikes have 45 seconds after their burn out to pre-stage. If a bike is unable to pre-stage after 45 seconds, the starter will invite the other lane to pre-stage and the round will be forfeited by the broken bike. Once you declare you are broken to the starter, you have officially forfeited your run and will not be allowed to continue even if you are able to fix the bike. Once the starter tells you that the other lane is broke, you can choose to make a pass as a broke bye or break the beams. 

SUPERSEDE: All SDBA rules will supersede any rule in the NHRA or IHRA rulebook. If SDBA does not have a specific rule in place, then we will consult the NHRA and IHRA rulebook for a decision. SDBA race director will make the final decision on any conflicts between the NHRA and IHRA rulebook. 

TECH INSPECTION: Pro classes will be tech inspected at the scales. Sportsman and ET classes will be tech inspected at the racetracks normal tech location. Tech inspection reserves the right to inspect a motorcycle before, during or after the event is concluded for any reason at any location at the track. If a bike is tech inspected at the water box or in staging and does not pass, the rider is given 2 minutes to make adjustments. The adjustment period will only be given to a bike once during an event; second infraction is a no run. 

UNSPORTSMANLIKE CONDUCT: Any racer that causes physical harm to another person, or acting in an unsportsmanlike manner is subject to be barred from all SDBA events for up to 1 year, forfeit all season points, and have to pay a $1,000 fine before returning to SDBA. Please handle yourself like a sportsman.

PROTESTS:. If any competitor believes that another competitor has intentionally broken the rules in order to gain an advantage they are allowed to open an official protest with SDBA tech. Protests are to be made immediately following any event that raises concern in regards to cheating. If the event is during a round of competition the protest must be made for the next round of competition for that class begins. If a competitor is found guilty in the protest they will be asked to leave the property for the remainder of that event. If a competitor loses to an illegal bike during competition that rider will be placed back into the active field in place of the rider who broke SDBA rules. In order to protest a Mechanical engine issue requiring any engine cover be removed from the engine the protestor will be forced to put up a $400 inspection fee. In the event the bike in question is found to be in compliance, the fee will go to the rider under question. If the bike is found to be illegal the fee is then returned to the protester. All Protests are at the discretion of SDBA tech and will only be substantiated with reasonable suspicion.
