The Open 2-Stroke Championship presented by Word Racing.

Professionally run. Grassroots focused.

Shifter Kart racing at Pat's AcresThe Open 2-Stroke Championship is contested over 5 or 6 rounds each year and run in combination with local series at Pat's Acres Racing Complex and PKA's McMinnville track, as well as other regional events in Oregon, Washington and Idaho.


Originally formed in 2016, the excitement continues to build in 2019, as we return to Pat's Acres for two night races, opening and closing events at the famous Mac track, and an exciting new addition at the Boise, Idaho Fairgrounds - part of their annual Motor Fest!


Three different tracks, Saturday night races, and Sunday races - great variety and a reasonable 5 race schedule that keeps it affordable, as well as a good spread of time between races to prepare.


We're bringing back the fun and smiles of affordable grassroots racing in the blazing fast 2-stroke classes. If you're bored with the slower LO206, and you're ready to move up, this is the place to be. Our semi-open rules allow the use of less expensive engines that are still competitive, so you can enjoy the thrill of 2-stroke power at a reasonable price level. We are also introducing the new Zamp O2s100 class for 2019 - the best bang for your buck.
