MOTION BY CIRCUITONE
D Force 1 MOTION
Competition-grade four-axis motion, sized for the rig you own.
180 kg of lift and 50 mm of tightly controlled stroke per axis.
Precision where it counts, not motion that feels like a roller coaster.
D Force 1 was built to inform. Deep, immersive motion that's responsive.
0-100 Hz puts real detail in your hands, from kerbs to grip loss.
Founded and raced by real and sim drivers.

WHY CIRCUITONE
Every Millimeter Accounted For
Most motion systems ask you to rebuild the rig around them. D Force 1 works the other way. It bolts to standard 8020 profile, runs one cable per axis, and disappears into the chassis you already race on.
Smallest Footprint in Its Class
At 257 mm end to end and 3.55 kg per axis, D Force 1 fits rigs that cannot take a conventional actuator.
Less Travel, More Truth
50 mm of stroke sounds small until you feel it. Short, tightly controlled travel resolves the details that make you faster. Kerb edges, grip breaking away, weight transfer, and more.
Lifts 180 kg Per Axis
Enough headroom to move a loaded cockpit without sagging under a heavier driver or a full-motion seat. Tested in gruelling, long races like iRacing's Spa 24, loved by top split drivers.
0 to 100 Hz of Detail
A wide frequency range separates a curb strike from tire scrub instead of blurring both into one buzz.
One Cable Per Axis
No polarity, no loom, no guesswork. Each actuator runs a single cable back to the LINK box.
Eight Screws, Full Install
A complete four-axis build uses eight screws and no adapter plates. Most owners are racing the same afternoon.
Installation
Yes, It's That Simple
D Force 1 mounts to standard 8020 aluminum profile. No adapter maze, no custom brackets, and no drilling into a chassis you paid good money for.

TELEMETRY LIGHTING
Race Data Where You Can Actually See It
Telemetry-linked LEDs put ABS, traction control, and flag states on the hardware itself, so you are not pulling your eyes off the apex to check a second screen.
ABS Activation
Your chosen color and flash pattern fire the instant ABS engages.
Traction Control
Map live TC state per preset or per supported game profile.
Flag Signals
Route yellow, red, and blue flags to their own LED responses.
Stacked Effects
Layer multiple telemetry triggers with priority rules you set.
THE HARDWARE
Circuit Manager Software
Full Device Ecosystem, Free Download
Tuning, presets, telemetry configuration, RPM lights, OTA firmware, and quick-launch flow are designed as one operating layer instead of scattered companion tools.
Device Tuning
Calibrate clutch bite point, separation points, paddle curves, rocker mode, and lock sync per axis.
Preset Library
Keep factory presets and personal setups side by side, then switch between rigs or car classes instantly.
RPM Lights
Build per-gear RPM thresholds with individual LED color rules and full rev-light behavior.
LED Telemetry
Bind button LEDs to ABS, traction control, flags, and custom states.
OTA Firmware
Deliver updates through the app with version confidence and no manual flashing workflow.
Game Launcher
Quick-launch supported sims with the correct device profile preloaded.
Short Travel, Higher Precision
Short, controlled motion preserves the detail that matters
Short travel does not mean less information. It reduces overshoot so grip changes stay readable instead of being buried inside large body movement.
8-15 mm
Short, controlled travel
Keeps tire-load changes, curb edges, and slip onset inside a tight readable window.
40-80 mm
Large body swing
Adds drama, but it can blur the first small signal that tells you grip is leaving.
Short & Precise
Detail stays readable
Smaller movement keeps timing intact so you can feel the first useful signal.
Large & Loose
Drama can mask detail
Bigger chassis swing feels obvious, but the first fine-grain cue arrives less clearly.
Road edge and curb detail
Initial impact stays sharp, separated, and easy to place.
The first hit blends into a longer body movement.
Grip loss onset
Breakaway starts to read before the slide becomes large.
The detail arrives later, after the chassis has already moved.
Weight transfer
Load build-up feels tied to what the tire is doing right now.
Motion amplitude grows, but the timing becomes less exact.
Frequency Map
Different Hz bands explain different parts of the car
Different frequency bands tell different truths. Low frequency carries weight and slip; higher frequency carries surface texture and the first hint of lock-up.
Built By Racers
Who builds it is the same group that pressure-tests it
Built with active sim racers and validated against the kind of stints that expose weak hardware, weak feedback timing, and weak software decisions.
