* The Air Cooled 100cc 2-cycle classes are new at PKRA. Details may be adjusted as we get experience

** World Formula “Limited” PKRA local classes allow running a Blue Ignition and allow any Drum/Can clutch (as with LO206 rules). All other IKF World Formula rules are followed.

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 any event cannot move back down to any other lower age class.
  • 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.
