SR-1 Millimeter-wave Radar System
SKU: MFP0216
Eyes forward. Radar watching your back.
SR-1 is an automotive-grade 77GHz millimeter-wave radar built for motorcycles. With four active warning modes and a detection range of up to 70 meters, it keeps a constant watch on the space behind you — through rain, fog, and darkness — so you can ride with your eyes forward and your confidence intact.
Developed on Real Roads, Not just in the Lab
The SR-1 Millimeter-wave Radar System started as a CHIGEE project in 2025 with a simple idea: build a radar system that actually feels right on a motorcycle.
For us, it was never just about detection. What mattered more was how the system behaved in real riding — whether the alert came at the right moment, whether it felt clear without being distracting, and whether riders could keep trusting it mile after mile.
That’s why, from 2025 to April 2026, the CHIGEE R&D and testing team kept taking SR-1 onto real roads, including motorcycle trips in different parts of the world. Those rides helped us continuously refine the warning trigger logic, making alerts feel more natural, more balanced, and better suited to real traffic situations. And with OTA update support, SR-1 is built to keep improving over time.
At the same time, both the light bar and the radar module went through multiple design revisions to become smaller, cleaner, and more refined on the bike.
SR-1 is the result of that process — shaped by real riding, refined through repeated testing, and designed to deliver radar awareness in a form that feels more natural for riders.
SR-1 Radar Compatibility with CHIGEE Displays
The SR-1 Radar is currently compatible only with AIO-5 and AIO-6 series displays.The SR-1 Radar cannot pair or connect with the XR-2 Display. If you use SR-1 with XR-2, radar warnings can only be viewed through the flashing indicator light, not on the XR-2 screen.
BUILT FOR HOW MOTORCYCLES ACTUALLY RIDE:
Unlike conventional radar systems adapted from automotive use, SR-1 is built specifically for motorcycles and the way riders actually move through traffic. It does more than detect what is behind you — it delivers earlier, more relevant warnings for blind-spot traffic, lane changes, overtakes, and fast-closing vehicles from the rear.
And unlike systems that only alert the rider, SR-1 can also trigger an active rear warning light to help make approaching drivers aware of your presence sooner. The result is a radar system designed not just to detect traffic, but to work more naturally in real riding conditions.
Up to 70m detection for wider rear coverage
SR-1 extends rear awareness beyond the immediate blind zone, helping riders detect vehicles earlier across a broader rer and rear-side area.
Four active warning modes
The SR-1 runs four independent warning algorithims simultaneously, each tuned to a specific riding scenario.
Note: The radar module and indicator light provide visual warnings only and do not produce soun alerts. To receive audible warnings, you need to pair the radar module with the CHIGEE Display and enable the sound alert option in the settings.
Blind Spot Detection (BSD)
Detect vehicles in your blind spot before you change lanes.
Once your speed exceeds 10km/h, SR-1 automatically monitors the blind spot area beside and behind your motorcyle. If a vehicle enters that zone, the system sends a visual and audible warning to help you notice nearby traffic earlier when changing lanes or riding in dense traffic.
Active Overtake Alert (AOA)
Know if another vehicle is approaching from behind before you move back into the lane after overtaking.
After you overtake another vehice, SR-1 checks the lane again before you move back in. If another vehicle is approaching from behind or remains in the blind spot, the system warns you in time so you can merge back more safely.
Lane Change Assist (LCA)
Get lane change warnings that adjust to your riding speed and surrounding traffic.
SR-1 adjusts warning timing based on your speed and the relative speed of surrounding vehicles. At higher speeds, alerts come earlier to give you more time to react. In sower traffic, unnecessary warnings are reduced so the system stays helpful without becoming distracting.
Rear Collision Warning (RCW)
Know sooner when a vehicle is approaching quickly from behind.
If SR-1 detects a possible rear collision risk, it sends a warning immediatley. This gives you more time to stay aware, keep your motorcycle stable, and react to a fast-approaching vehicle behind you. Warning sensitivity can also be adjusted to better match different traffic conditions and rider preferences.

Warn Yourself - And Warn the Vehicle Behind You
Most blind-spot systems alert only the rider. The SR-1 takes it a step further. An integrated high-brightness strobe light is built directly into the radar module. When a vehicle is detected closing dangerously fast from behind, the light flashes automatically — alerting the approaching driver to back off before a collision becomes likely. Particularly effective at night or in low-visibility conditions, this turns the SR-1 from a passive sensor into an active road-safety device.
Auto-Dimming Indicator Lights
An onboard ambient light sensor continuously adjusts indicator brightness. In direct sunlight the lights punch through the glare & at night they dim to avoid dazzling you or traffic behind. No manual adjustment needed.
Flexible mounting, easier fitment
The bracket can be mounted in either orientation, allowing upright or inverted installation to suit a wide range of motorcycles.
Pairs with Compatible CHIGEE Displays
When paired with a CHIGEE display, SR-1 can bring radar information onto the screen in real time, giving you another layer of situational awareness beyond the warning lights alone.
You can also adjust selected warning parameters to better suit your riding style and environment, making the system feel more personal and more relevant to the way you ride.
Tune warnings to match your ride
SR-1 lets you adjust how the system warns you, with control over the sensitivity, activation speed, and alert intensity. Through the CHIGEE display or mobile app, you can tailor alert behaviour to suit different roads, traffic conditions and riding preferences.
The result is a warning setup that feels more relevant, less distracting and better suited to the way you actually ride.
Note: This feature is expected to become available late MAy to early June. Please stay tuned for the official release notice.
Built to improve over time (OTA)
SR-1 supports Bluetooth OTA updates, allowing the warning system to keep evolving through future refinements. As more riding data and real-world scenarios are incorporated, alert logic and detection performance can continue to improve over time.
Built for long miles and bad weather
The Sr-1 radar module is built to handle tough riding conditions, with IP68 / IP69-rated protection against rain, dust and prolonged outdoor exposure. Sealed for long term reliability, it is made to keep performing through changing weather, dirty roads and everyday use.

Standalone Indicator Light
Every SR-1 includes two standalone
indicator lights as standard. They provide radar warning alerts without the
need to replace existing bike components, making them an easy fit for a wide
range of motorcycles.
Simple to install and flexible to
mount, they are the default setup for riders who want a practical,
ready-to-fit solution straight out of the box.

CG Radar Mirror (Optional)
For riders who prefer a cleaner, more integrated
look, the optional CG Radar Mirror builds the warning light into the mirror
itself. It delivers the same core alert function in a more seamless, more
refined setup.
Note: If the optional CG Radar Mirror is installed,
the system will use the built-in mirror indicator automatically. The included
standalone indicator light does not need to be installed.
