The Open 2-Stroke Championship was created in 2016 to bring back the fun and participation in local kart racing. With a focus on making the fast 2-stroke classes affordable and open to most all types of 2-cycle engines, we are giving people a place to race competitively with either older “obsolete” engines, or the latest engines. Professionally run, but grass-roots focused, we welcome all levels of Karters from the weekend warrior simply looking to hangout with his friends and have a great time, to the semi-pro Karter looking for competition and track time to prepare for big events such as the SKUSA Super Nationals. This is a series that keeps costs to a minimum, and where camaraderie off the track and wheel-to-wheel competition on the track is the rule.
