About SigmaWhich motion system is right for you?
The DK2 motion system offers exceptional at-home haptic performance, combining the mechanical and electrical capabilities of our flagship DK+ line in a more compact and cost-effective design.
The DK2+ motion system builds on the DK2 platform, featuring upgraded, larger motors that deliver sharper bump and curb feedback, faster directional changes, and a smoother, more natural driving experience.
The DK6+ motion system takes it even further, incorporating the same upgraded motors while adding 4" of additional travel—perfect for immersive experiences in off-road racing, rally, and flight simulation games.

Sigma has an interesting approach to Sim Racing motion which translates pure telemetry data to the seat of your pants rather than using canned effects like you find with D-Box and other motion systems.

Why DK Motion Systems?
01 | Mechanics
DK systems are made from billet using precision CNC equipment. This prevents piston deflection, providing long service life with minimal maintenance required. This design enhances vibration transfer to the chassis. Featuring the industry’s largest ball screws and a 2" electroplated piston, our systems ensure smooth, quiet, and durable performance, even under side-loading.
02 | Software & Algorithms
Our proprietary algorithms deliver only game-provided motion, without artificial effects, avoiding false positives and maintaining a sense of realism. The remote UI app enables real-time tuning from your phone. Our Dynamic Scaling algorithm optimizes actuator travel, enhancing experiences in flight and off-road games.
03 | Electronics
We are the only company using a 75-volt DC system, enabling small yet powerful motors and improved cable management with thinner cables. Our system uniquely allows disconnecting and reconnecting power/data cables for easier installation and routing. A 32-bit real-time ARM core processor handles velocity, acceleration, and jerk calculations, setting us apart in the industry.
