1B Licensing
1. You may obtain an ASMA Roadracing license by filling out a license application either at an event or you
may download a form online. In addition, ASMA will send all current license holders a renewal form at the end
of each year.
2. All licenses are good for the current racing season. All licenses expire on December 31st of the year they are
3. To obtain an ASMA license, you must pass a race clinic. ASMA holds a race clinic on Saturday morning at
each ASMA roadrace. In addition, we have many license clinics during the off season. At the completion of the
clinic you can purchase an ASMA race license, receive a number and enter races.
4. If you are already licensed, we need to see your current race license or a photocopy of your license.
5. One event licenses. One event licenses are available at a cost of $10 per event. A one day license entitles you
to points and contingency.

1C. Penalties
1. In addition to fines and other penalties, ASMA Officials have the right to revoke your license, either
temporary or permanently for any offense deemed unacceptable.
2. Rough riding. This is defined as intentional contact with another racer. We understand that accidents happen,
we also want to make sure our racers are safe. Questionable riding can result in anything from a warning to loss
of your license and forfeit of your entry fee, penalty is up to the head race official.
3. If you have a problem that’s not getting resolved, don’t yell at our staff; take your problem to the head
official. Failure to do so may result in penalties.
4. Speeding in the pits. Pit speed is 5mph. Speeding will result in fines. Fines are $20 first offense, $50 second
offense, $100 third offense. All speeding fines will be put into a purse for one of our races. Blatant speeding,
ASMA reserves the right to penalize either higher fines or suspension of racing, or both.
5. Cutting the course. Any rider that goes off track and cuts the course and re-enters the track with an advantage
will receive a stop and go penalty. Stop and go penalties will take place in the hot pits. When serving a stop and
go penalty, you must come to a complete stop where directed by the race official.
6. Jumping the start. Jumping the start will result in a stop and go penalty.
7. Either you or a representative must attend the riders meeting each morning. Failure to attend the riders
meeting will result in possible suspension from riding that day.
8. Racers are subject to represent both themselves and ASMA in a fair manner, both on and off the racetrack.
Failure to do so may result in fines, suspensions or both. The ASMA head official has the final say in these

1D. Appeals and protests
1. A fine or penalty may be appealed by using an appeal form available from race officials. Appeals will be
brought to an appeal board made up of both racers and officials and put to a vote.
2. Protests may be made to determine eligibility on competitor’s motorcycles. To file a protest, fill out an
official protest form available from ASMA officials. Cost for a protest is $15 for visible infractions (anything
that can be seen without removing parts from a motorcycle), $25 for all other non internal engine protests and
$700 for internal engine protests. If the motorcycle in question is determined legal, all protest money is turned
over to the owner of that motorcycle for re-assembly. If it is determined illegal, protest money will be returned
to the person who filed the protest. If motorcycle is deemed illegal, its owner will lose all points for that event in
which the bike is illegal.

1E. Rules, how they’re made.
1. Generally speaking, rules are made either by committee, voting, or by ASMA staff. If a rule is made by
ASMA staff, it is most likely made by Roger Heemsbergen, who has raced for 33 years. If it is made by voting,
it is most likely done at either a riders meeting, or done by a poll through the message boards at ASMAracing.
com. If it is done by committee, we usually pick 5 racers who have ridden with us for at least a year to help
make decisions. It’s not always the same 5 racers, we want everyone to get involved with how the series is run,
so don’t be surprised if we ask YOU to help us make rules or decisions.

1F. Championship Points
1. Championship points are awarded to participants in each event. In addition to class championship points,
riders are also awarded overall points for each class raced, with the exception of the Beginner race which doesn’t
award any points.
2. In combined classes which don’t use amateur and expert status, such as Lightweight GP, Lightweight
Superbike, Formula 40, Heavyweight Twins, Kawasaki 650 Spec, Modern Vintage and Team Sprints, a riders
finishing position will be awarded to amateur or expert overall points, depending on their status.
3. Top 10 Plates. Numbers 1-10 are awarded to the championship standings in Formula Arroyo (ULGP). This
means racers with a low number will always be the fastest racers, something to be proud of.
