This page contains a brief overview of classes offered. We basically follow the guidelines set forth by AHRMA (the American Historic Racing Motorcycle Association). Changes have been made to women's class and kids classes have been added. For further details an online rulebook can be found at www.ahrma.org.

Rules

Noise Levels

All bikes must have silencers. Also recognize that even though some bikes have silencers they are obnoxiously loud and some measure should be taken to keep them to a tolerable level. Some of our events are close to homes, be considerate of our surroundings and others.

Pit Riding

Must be done in low gear. As this series grows, we have more people milling about in the pits. Remember this and keep your pit speeds down to first gear. Parents, you will be responsible for your kids and their riding habits. Almost every track has a place for clean out and test as well as kids to ride. The pits are not it.

Drugs and Alcohol

If you are racing then do not drink ANY alcohol before your races are over. If you partake of illegal substances of any sort, DO NOT DO IT AT MOVMX EVENTS!!! Besides the obvious safety concerns it’s illegal and we are guests on the private property of others. Please respect the kindness of these people who let us race on their land.

Helmets

If you are on your race bike, your helmet should be on your head. Whether your racing, warming it up, or (I love this one) checking your jetting after just putting the carb back together. Put your helmet on.

If you are under the age of 18, your helmet MUST be on your head. Parents again you are responsible for your kids. Teach them safety please and keep injuries to a minimum.

Numbers

Please have the same number on all of your bikes. If you have more than one bike that you ride yourself please have the same number on each of them. The more numbers that you have on more bikes makes it harder to score each race. As we have gotten more and more riders, the duplicate number problem has become an issue. If you think someone else may have the same number, call me and ask. We can Fix it now before race day and make things easier for all of us. Also it is your responsibility to make sure that the numbers are legible. If the scorers can’t read it, you don’t get scored!

Sign Up

Verify all information on your sign in card. Please make sure it is legible. Make sure to use one card for each class. If your number has changed, PLEASE MAKE NOTE OF IT. This is the information that is being put in the computer to score the races off of. If you don’t tell us what your number is, we can’t score you. The most important information is your name and number. Also make sure that you understand the forms you are signing. The release forms are for your protection as well as the owners of the facility, but you must understand that “this is a dangerous sport and you are responsible for your own decision to race”. You must sign your entry card and the release from as well.

Kids Sign In

This year there will be a separate sheet for the kids and their parents to sign on race day, But “WE MUST HAVE A PARENTAL CONSENT FORM SIGNED BY BOTH PARENTS ON FILE BEFORE THE KIDS CAN RACE!” If you plan on having your child under the age of 18 race this year please get one of these release form either at the track or contact us and we will mail it to you.

Practice

Due to the increasing number of riders there will be 10 minute practices broken up by novice and women riders, Intermediate and expert Riders, Schoolboy classes and 50cc. A second round of five minutes practices will follow. Ladies and gentlemen, not taking practice is the fastest way to insure injury. Make sure that you are signed in in time to practice and the best thing if you can is always walk the track.

Riders Meeting

This is information for you for the day and usually concerns your safety. Starting procedures, races order are important things. Please take this part of the day seriously. Every race of 2003 at least one person got into the wrong race. Riders meeting is to clarify any questions and make sure the guy next to you on line have the same understanding that you do as to what’s going on.

Complaints and Protests

If you feel that you have been wronged on the race track, or that someone has cheated you, or that there is a scoring problem, there will be a form this year so we can keep track of things. They will be located on the trailer door. These problems should be taken up with the referee, (Curtis). Do not interrupt the scorers! These people are doing their best to keep things straight as you guys are racing. Interrupting them during races just makes things worse.

Bike Changes

There will be a board on the trailer door. If you change bikes during the day due to technical difficulties or whatever, we must know your name, what race number you are in, what the parked bike number is and what the new bike number is. Lap scorers do not need to know. But the finish scorer and the starter will. (Finish scorer is the person entering the races into the computer, and the starter is the person checking you in at the starting line.)

Classes

At this time classes are to be kept parallel to the rulebook of the American Historic Racing Motorcycle Association. We have an agreement to use their rulebook for machine guidelines and class structure. This facilitates the ease of movement from MOVMX to AHRMA regional and national events. The exceptions to this are as follows:

  • In a couple of the classes, specifically the Plus 60 and Plus 70 I have pretty much dropped the vintage and post vintage split. If you are 60+ years old and want to race motocross, I think you have earned the right to cheat on suspension a little bit.
  • The women's class is open to all bikes both vintage and post vintage. The more the ladies like it on bikes that make them comfortable, and feel in control of the machine the better it is for all of us. This also makes the class big enough for the women generally to have a gate to themselves. Let’s face it “If Momma ain’t happy, ain’t nobody happy.”

Schoolboy Classes

The kids program is designed to be for the kids of vintage racers. It is not the focus of our program and is not designed to launch anyone into a pro career. It is only to make the sport a family oriented thing again.

Classes at this point are 50cc for the little guys. And 65cc plus for the larger kids. The 65cc plus class is also split for modern and vintage and limited to 100cc maximum displacement. At this time we will not split two and four stroke. However if it becomes an issue I can always change that down the road. I will make class structure changes to kid classes only. The focus of the kids classes are to introduce them to racing and competition. Being flexible to accommodate the needs of the youth will happen on the fly and decisions will be made by me (Curtis) as the need arises. The term vintage has meant pre-74 or "of like design". Due to the rarity of pre 74 100cc bikes, I will change that to 1979 or earlier, twin shock. This will allow the use of Hodakas, Suzuki DS, TM and RM 100s, Yamaha MX and YZ 100s, Chaparrel, Kami, Indian Steen and all other Fuji motored machines. All single shock and later bikes will be considered modern. This pertains to kids classes only.

Depending on the turnout of youth, the 50cc class will run separate from the 70cc+ class. Normally all 70cc+ kids will run together but scored separately.

Cut-off For Eligible Bikes

Generally we have set the parameters with no disc brakes. This in the past has allowed a few riders to modify bikes they already have back to drum brakes event though they may have been originally front disc brake. However this year there will be a cut off year of 1985motorcycles with drum brakes front and rear. This allows those who already have modified those machines to keep racing them, as I can’t go back on my word to those people.

What is Vintage, What is Post Vintage: Vintage bikes are generally Pre 1975 with a few “like design exceptions” Mostly the bikes that were before the longer travel era. These bikes will have 4” rear and 7” front suspension travel. Post vintage bikes will be 1975 and later. Bikes that push the travel over that 4” mark and on. There is more information available on the website about class structure.

Q. How do you set up the classes? This is not a rule but you should know how we try to do things when races are structured.

that are most important to race order is keeping like speeds together. For Safety reasons, I will almost never have an Expert rider on the track the same time as a novice. Most races will have combined levels of novice and intermediate or intermediate and expert. This is the first and most important thing to me. It is for the safety of all riders and spectators.

, displacement classes and age classes are seldom run together. For example, the Open Sportsman class is almost always the same entrants as the Plus 40 class. So if you want to share a bike with someone, one rider in displacement and one in age class is usually a safe bet on having some time to change riders.

is the separation of Vintage and Post Vintage bikes. This allows for a better break of races so riders get more rest time in the pits between races. Unfortunately riders with both Vintage and Post Vintage bikes run the greatest risk of getting back to back motos. The race format will generally be run with an alternating vintage, post vintage race order.
