The ProKart Challenge offers a broad spectrum of classes that provide a place to race for drivers of all skill levels and racing experience. The impetus of the series is to offer a friendly environment where anyone can race with virtually any kart package.
Notes: (1) Participation is contigent upon SKUSA racing license approval in your chosen class (except for the LOCAL OPTION class, which does not require a SKUSA membership/racing license). See MEMBERSHIP page for details. (2) Participation in the local option classes will be closely monitored, and we reserve the right to eliminate any or all of them from the class lineup without sufficient interest. (3) Trophies will be presented at each race to the top 3 finishers in each class, as long as there is a minimum of 5 entries per class.
According to the SKUSA Rulebook, the driver's racing age for purposes of class eligibility is based on the age attained by the last day of the racing year. (For example, any racer that turns 8 by the end of 2013 is now eligible for TaG Cadet; anyone turning 13 by the end of 2013 must promote to a Junior class.)
