PKRA Racing Classes

The following is a list of the current classes being raced at PKRA.
Note that you will register for the particular class (left-most and bolded), and not the specific engine.  For example Tag100 Senior, Shifter -Spec125, Kidkart – Other.  If there are differences in weight, they will be marked on your pre-tech tag in pre-tech.

Our primary rule set is IKF, but Club rules supersede any other rules.  Examples include Tires, Fuel, minimum Weight,  and Ages.

Minor Age Rules:

  • Drivers that become 8, 12, or 16 during the calendar year (aka competition age), have the option to move to the next higher class at any time during that calendar year (aka option year).
  • Once a driver moves up to the next higher age class in a PKRA club race cannot move back down to a lower age class within Tag or 4-cycle groupings.
  • Parents may pettition to get a waiver to move up early. IKF must approve the pettition, but the process starts by making a request to the board at directors@pkra.com.
  • Kid Karts must not be on the track with any other classes. Junior 1’s may be on the track with Junior 2’s, but no other classes.
