Revolutionize Your Sim Racing Experience with the DK2 Motion System - The Ultimate Motion Simulator for Gamers!


Get ready to take your racing experience to the next level with the DK2 Motion System - the ultimate solution for serious sim-racing enthusiasts, drivers, and researchers. With cutting-edge technology, modern controllers, and ultra-low total loop latency, the DK2 delivers more than double the performance of other turnkey motion systems, all while costing only half as much.

Featuring the same design and construction as our industrial-grade motion systems used in full motion vehicle simulators, the DK2 is engineered to provide the most realistic and representative vehicle motion feedback possible. Don't settle for anything less.

Experience unparalleled responsiveness and precision with the DK2 Motion System - the most advanced and cutting-edge solution on the market. By taking a modern approach to signal processing and motion control, we've created a system that captures every elevation change, vehicle movement, surface change, and gear shift with breathtaking accuracy, reproducing them within an incredible 2 inches (50mm) of the available mechanical stroke.

All motion systems are built to order and ship once rigorously tested. Purchase includes all duties/fees. Get yours now!
