News / Updates

All 250cc classes and above - consider this your official notice: You'll be automatically entered into the 2026 Red Bull Dirty Dozen Series at Thursday Night Motocross. No extra sign-ups. No barriers. Just sign up and race.

This year raises the stakes. Riders will battle it out across the *12 race series for more than just bragging rights - limited edition Dirty Dozen award plaques will be earned, not given. And those who rise above the rest, the ultimate prize awaits: The Champions Award reserved for the best of the best. To cap it off, Champions will be invited to an exclusive Red Bull hosted dinner - a night built to celebrate grit, speed, consistency, and the relentless drive it takes to come out on top.

The gate drops in April 2026, the question is - who's taking their place at the table!

• * Anniversary Race July 23rd is a double points night.
• AMA waivers must be signed.
• Series Leaders must wear RBDD bibs.

2026 TNMX Race Schedule Announced! Swing on over to the schedule page to check it out!

Riders MUST have an AMA card prior to sign-up at TNMX. This is much like the current MXNW Cards we issue today, which will no longer be accepted. The Youth waiver requiring both parent signatures is mandatory or the rider will not be allowed to race the event. This is something ALL AMA sanctioned tracks must adhere to.

• Youth Membership is $35
• Adult Membership is $49

Complete the AMA membership application, print & bring your receipt to sign-up registration Thursday. Riders will NO LONGER purchase their race entry at the main gate. Effective this week, all race entries will be purchased at the TNMX tower and waivers must be signed. Race entry fees are: $15 all 50cc classes, $25 big bike Amateurs, $35 Pros. AMA does offer an annual waiver (youth riders only) that would be listed on the rider profile that must be completed online and a copy provided to TNMX at registration.
