The A Main is the target. The B Main keeps your weekend going. The AM Open caps each A Main at 15 riders, with the class championship and AMA #1 plate on the line. Miss that cut? There is still a B Main to race. Both A and B Mains stream live and free on @insidermx , so the people cheering from home can follow along. Get entered at AMOpenSX.com and share this with a racer planning the trip. #AMOpenSX #AmateurSupercross #ArizonaCyclePark #MotoFamily Supercross taken in Arizona Cycle Park by @amopensx

We have gone deep into building, testing, building, testing. Constantly waking up and trying to make it better for the racers. Some things work; some don't. We feel like we have gotten to a pretty good place with the tracks and are going to start working on making it pretty now. ⏩ We will open a limited practice session on 9/20 for multiple classes. For this first practice session, we will split into different classes and limit the number of bikes on the track at one time. No whoops will be on the track for this first session, so riders can learn without having to go around them. We will limit the number of riders for this practice session. The registration link is in the bio. ❎ No beginners, no refunds. Big reminder for those on 85cc and down - this is NOT THE FINAL COURSE for YOU. We'll make A LOT of changes for your race weekend. So please ride within your ability ♻️ On 10/3 and 10/4, we will also have a practice, and the whoops will be in for that session. ⬇️ If you want to lock in that $55 pre-reg special, we recommend you do it soon, as that price will change as we get closer, along with something extra for all racers. taken in Arizona Cycle Park by @amopensx

This October, the AM Open of Supercross is bringing a brand-new format to @arizonacyclepark — on @elitomac Supercross track. Two weekends. Two completely different race experiences. One goal: better racing. Weekend One — October 17th and 18th — built for the fast riders. We’re talking A, B, and C big bike classes, plus SuperMini racers, all going head-to-head on a weekend tailored for speed, competition, and serious racing. Then, Weekend Two — October 24th and 25th — the next generation takes center stage. 85s, 65s, 50s, and Women’s classes hit the gate for their chance to experience real Supercross racing on Eli Tomac’s Supercross track at Arizona Cycle Park. By splitting the event into two weekends, we’re giving every rider a better experience — more focused racing, smoother schedules, and more time on the track. This isn’t just another motocross race. This is Supercross. Two weekends. One incredible track. And your chance to experience the AM Open of Supercross. Registration is open now. Head to AMOpenSX.com, pick your class, and get yourself on the gate. October 17th and 18th. October 24th and 25th. Arizona Cycle Park. Eli Tomac’s Supercross track. Register now at AMOpenSX.com. We’ll see you on the gate. taken in Arizona Cycle Park by @amopensx
