Arizona's Premier Off-Road Championship Series
Transponder Purchase and Information
All racers please note:
  • The AMRA big bike series is using a new transponder reader/scoring system for the 2012+ seasons
  • The transponders from 2011 and previous years (the cigar-style transponder) will NOT work with our new system
  • This means all riders will need to purchase transponders for the 2012 season and beyond
  • There is an option in the link below to purchase a reduced price transponder with the trade-in of your old transponder

This new setup should allow for more accurate scoring and also significantly reduces the price of the transponders to racers (the old transponders cost $35 each).

Once you've made your purchase via this site, we will note that you have paid and you can pick up your transponder at the next race. We will not be shipping these out to riders.

Transponder Tips:
  • Transponders should be mounted on the underside of the helmet visor
  • Transponder needs to be at least an inch away from the rider's body
  • Helmets with metallic paint may cause interference, so be sure to have an AMRA official inspect your transponder mounting location
  • Handle the transponder carefully prior to mounting so that the antenna does not get damaged
  • Cloth tape (no metal) can be used over the transponder to ensure adhesion to helmet visor
