Endurance

NJ MiniGP Endurance Races will include 3 different Race Classes— Stock 100 Class, Stock 150 Class, F2 Class, and Outlaw Bikes —with 1st Place, 2nd Place and 3rd Place awards for EACH class. F2 and Stock 100 bikes must conform to the rules listed above. “Outlaw” bikes are "Big Bore Machines that started life as a CRF150F". NJ MiniGP Officials will determine whether or not entries are F2 Class legal or Outlaw.

We will be holding very firm on engine displacements of 150cc air cooled four stroke, 130cc liquid cooled four stroke, and 72cc two stroke for the F2 class. We need to adhere to this rule structure for many different reasons. If there are any questions at all please don’t hesitate to contact us at info@njminigp.com.
