December 31st of the year they are purchased.
3. To obtain an ASMA license, you must pass a race clinic. ASMA holds a

4. If you are already licensed, we need to see your current race license or
a photocopy of your license.

1. . In addition to fines and other penalties, ASMA Officials have the right
to revoke your license, either temporary or permanently for any offense
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
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, 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.

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
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.
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
