Attention All TNMX Riders
6/27/25
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 $29
- 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 remains as is, $15 all 50cc classes, $25 big bike Amateurs, $30 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.

RBDD Registration Open!
4/29/25
Red Bull Dirty Dozen is a unique amateur motocross series taking place within the existing TNMX season at PIR. Out of the 24 regular season races at TNMX, 11 will be designated RBDD Races with the famous TNMX Anniversary Race counting as double points making it a dirty dozen! Register online today for the RBDD series.
E-Bike Announcement
4/24/25
In support of current AMA ruling, TNMX will allow and score like all other bikes, 50cc electric motorcycles in the 50cc class skill levels. Due to AMA safety guidelines, unfortunately electric big bikes (Stark Varg / Dust) will not be allowed to compete at TNMX in 2025. Example of current AMA concerns are their silent motors (other riders will not know where they are during a race) and adjustable power programs on the bikes.
2025 Race Schedule Announced!
