Red Bull Dirty Dozen is a unique amateur motocross series taking place within the existing TNMX season at PIR.

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.
