DK2+ Motion System
DK2+ Motion System
USA domestic shipping is 3-5 days. All international shipping is typically 5-7 days.
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.

Sigma DK2+ Motions Systems feature
All DK motion systems are made in the USA from a solid piece aluminum for optimal strength, durability and the best haptic feedback translation. Machining from billet aluminum is significantly stronger over other methods of production such as casting, bolted assemblies or 3D printing. Each system also features a solid 2” OD steel piston and oversized ball screws for optimal smooth performance and long service life with no maintenance required. The DK system installs in less than 30 minutes to almost any aluminum extrusion with our own billet aluminum brackets and components.
Motion Specific Electrical System
Sigma uses premium American-made Teknic integrated motors specifically tuned to run Sigma’s advanced motion algorithms. At double the price of conventional motors, the servos have three times the performance of conventional motors. We are also the only company to feature 75VDC electrical architecture for various performance standards. Each motor is optically isolated guaranteeing zero electrical or magnetic interference. Cable lengths from the controller to the motors can go up to 150-feet and the controller connects via an ethernet cable to the computer for optimal signal integrity. The controller is switchable between 120/240v and ships with power cables and accessories specific to your region.
Specialized Motion Software
Sigma takes a first principles approach with our motion software and algorithms. We design, build and develop all our embedded and motion software in-house. This allows us to achieve absolute control of our simulation specific control of its mechanical and electrical integration. Our software features specialized motion layers and unique algorithms to achieve what we call Motion Integrity or the most accurate representation of simulated motion. Pitch, roll, heave, environment, and our True Haptic engine and road vibrations are some of the best in the industry. Our software also installs quickly and has automatic over-the-air software and firmware updates. Remote tuning and control of the system is convenient and can be done in real-time with a secondary device without having to stop and exit simulation software.
Pure Algorithms no Effects or Gimmicks
Velocity Trap Algorithm
Our base motion algorithm is unique to Sigma and provides a smooth and natural motion representation. Available to all
DK motion systems.
Dynamic Scaling Algorithm
This algorithm allows for the full use of the actuators available stroke. Allowing all of the motion layers to be intelligently represented at all times.
True Haptics Algorithm
Our first principles approach to high frequency vibrations with no canned effects. Focusing on pure signal which results in less tunning and more driving.
