2025 Michigan Nitro Nationals

The AMRA brings the spectacular Penngrade1 V-Twin Drag Racing Series back to Michigan! US131 Motorsports Park, in Martin, Michigan, will host the 1/4 mile battles between the fastest American made motorcycles on earth. 230 Mph Nitro powered machines will shake the ground as they race for the 1320' mark along with extreme Baggers, no-bar Outlaw and Hot Street bikes, several Index classes and the very popular Dial-In Eliminator class. For those thinking about racing for the first time, we are here to make that experience smooth and fun. Joining the AMRA and registering to race is easy and both can be done online or at the event. We are always willing to help in any way either before or during the course of competition.
With each ticket offering full pit access, you'll have the opportunity to get a close-up look at what makes these bikes fly as well as the riders that pilot them. Kids under 12 are free so bring the whole family to this iconic track for a weekend of extreme excitement.
