AMB (Transponders)

OMRRA uses AMB sports transponders for all race and practice timing and scoring.

Racers are required to mount a properly functioning transponder to the front fork leg of their motorcycle whenever they are on track, and to have that transponder number linked to their OMRRA Track Intelligence account.

A limited number of AMB rechargeable units are available for rent in the second floor of the PIR Pro Pit tower each race weekend for $25 daily or $50 for the weekend.

 Reservations may be made in advance by contacting [email protected].  Rentals are first come first served, and availability is not guaranteed. 

 Transponder units are available for sale or subscription through  

The OMRRA system supports both the Classic (Flex, 260 and 260R) and the new TR2 & X2 transponder for motorcycles.
