FAQ 1

The DK2 is our optimal motion solution for home setups with a total simulator mass of 500lbs or less. The actuators are made of billet and feature 2" of travel. The system uses the same algorithms as the DK2+ and DK6 to accurately represent motion or what we call Motion Integrity.

The DK2+ and DK6 use larger Teknic servo motors, which output more power and better represent motion and haptics with simulators of up to 800lbs. Hence the DK2+ and DK6+ systems are suited for heavier rigs, heavier drivers or for sim racing centers where the total system weight is always an unknown.

The DK6+ uses the same motor as the DK2+ but has triple the stroke or travel and is better at representing the natural suspension travel and flight simulation telemetry. More technical details can be found here: DK System Comparison - Sigma Integrale
