Sigma Integrale DK6 Motion System

Sale price$6,400.00

Chat With An Expert




The DK6 system uses the same powerful motors as the DK2+ but has 150mm (6”) of actuator travel. The long travel is suitable for simulating high amounts of suspension travel (dirt ovals, off-roading) or environmental pitch and roll (flight). Although physically much longer, the DK6 is manufactured using the same mono-block machining process as the DK2 and DK2+.

The DK6 motion system is a professional motion system for racing and flight simulators. The system shares the same design and construction as our industrial-grade motion systems used in our full motion vehicle simulators. Additionally, DK6 is mechanically and electrically engineered around our unique motion algorithm to provide the most realistic and representative vehicle motion feedback.

DK6 takes a modern approach to our 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 150mm (6”) of the available mechanical stroke.

If you do not have an available network port on your computer. Please feel free to use a USB to Network adapter such as this model available on Amazon.

All motion systems are built to order and ship once rigorously tested.

Upcoming Integrations

More integrations coming soon. Our unique algorithm approach requires accurate tuning to ensure optimal and accurate motion response to signals generated by the software. All motion layers happen in real-time within health and safety limitations. Initial customers get their choice and preference of titles to be added.
