Double the performance at half the cost of other turnkey motion systems. Utilizing modern controllers with low total loop latency with no distracting effects or gimmicks.

Similar to our DK2 motion system, the DK2+ is a pure motion system for serious sim-racing enthusiasts, drivers, researchers and sim centers. The system shares the same design and construction as our industrial-grade DK-X motion systems used in our full motion vehicle and platform simulators. All our systems are mechanically and electrically engineered around our unique motion algorithms to provide the most realistic and pure representation of vehicle dynamics without relying on pre-recorded canned effects.

DK2+ takes a modern approach to signal processing and motion control to create the most responsive system on the market. Every elevation change, vehicle movement, surface change and gear shift, is captured and reproduced within 2” (50mm) of the available mechanical stroke. (Full Send Video Proof)

The DK2+ was originally created to serve many sim centers around the world. The larger motor is capable of 800 lbs. (360 kg.) of total supported mass and hence can support a larger variety of drivers or exceptionally heavy rigs. The DK2+ continues to be the go to motion solution for sim centers or for professional users looking for that little bit more.
