What is your refund policy?

If you sign up for a race and for any reason are unable to attend you will automatically be put on a rain check list that allows you to use the credit for a future race within 6 months. After six months that rain check will expire. There are no cash refunds. In the event of a raincheck, you cannot sign up online. You will need to sign up at the race track in which you will be credited for your previous missed event.

What if I already bought a membership in 2019?

Swapmoto Race Series will honor all memberships from TWMXRS for 2019. If you have already purchased their membership your good to go!

Which classes race on which track

Our races offer a unique format where we race two tracks at the same time. This allows for the beginner riders to challenge their skill on a safer more forgiving layout and it gives the faster riders a chance to compete on a track that fits their skill level. Best of all it makes our schedule much quicker. No other race event can get through 60 motos in one day like Swapmoto Race Series. When you visit the pre registration page for your event the classes will be laid out separately to show which class is on which track.


We always plan to run our events with rain in the forecast. The weather forecast constantly changes day by day and we can run an event with some rain.

If the forecasters are calling for a big storm like 1 to 2 inches of rain for the weekend we will evaluate and try to make a decision by Friday/Saturday morning prior to the event.

Can I bring my registration/waiver form pre filled out?

Yes, please feel free to download the form HERE print out and complete all fields. If you miss pre registration this is the easiest way to speed up the process on race day. Also if you decide to pre register you can complete only the waiver portion of this form and that will make things quicker as well.

Is your event suitable for all ages?

Our race series offers classes from 4 years old up to 65 years old. We also have skill levels to each age bracket from true beginners all the way up to pro. Swapmoto Race Series is for every rider and our staff can be very helpful when it comes to getting through your first day at the races.

What about the Mini Major?

​Without a doubt we will be running the Mini Major on November 7-10, 2019. This concept and event have been a great way to give back to the younger riders in our community. We also have a HUGE surprise up our sleeve…

Moving up riders in classes

Class winners in the starter classes get moved up at each event and all other classes get moved at the end of the series. All series class winners in the beginner classes will be bumped up at the completion of the series. We have different parameters for each class on bumping racers up to the next level (example, we move up beginners at a faster rate then the novice or intermediate classes).

Who is CMXRS?

CMXRS (California Motocross Race Series) is the same team you are used to seeing every weekend. Craig, Cherry, Carrie, Heather, Taylor, Dillan, Jen, Andy and Aaron will all be there to make sure your race experience is as good or better than it’s always been. Think of CMXRS as the promoter/production team running the race.
