SR-1 is a millimeter-wave radar system that helps you keep track of vehicles approaching from behind. Use it with the included warning lights, or pair it with a compatible CHIGEE Display for on-screen and speaker alerts.
Choose your setup
Standalone use
You don’t need a CHIGEE Display to use SR-1. The radar sends visual warnings through the two external indicator lights. The radar and lights do not produce sound.
With a CHIGEE Display
SR-1 pairs with AIO-5 and AIO-6 series displays for on-screen radar warnings, settings and sound through the display’s built-in speaker. You can use the radar and display without fitting the external indicator lights.
XR-2 does not support SR-1 screen pairing. If you use an XR-2 on your motorcycle, use SR-1 independently with its external indicators.
What’s in the standard kit?
SR-1 radar module.
Two external indicator lights.
Required wiring and mounting accessories.
Check the SR-1 product page for the package you’re ordering.
Install and connect SR-1
Follow the SR-1 user manual before fitting the system.
Mount the radar securely at the rear, horizontal and facing backward, 30–100 cm above the ground. Keep its view clear of luggage, body panels and other accessories.
Position the warning lights where you can see them from your normal riding position. Use your existing mirrors or the optional M10 warning light brackets.
Use the supplied harness and the standard battery and ACC wiring.
Power and wire your SR-1 radar covers standard wiring and links to a rider’s ezCAN installation video. The video is user-tested reference material; research any alternative setup for your own motorcycle. We recommend the manual’s standard wiring.
For pad sizes, cable routing and replacement parts, see Mount, replace and troubleshoot SR-1 warning lights.
Pair a display and understand the alerts
On a compatible display, open Settings → Function → Blind Spot Monitoring → Millimeter-wave Radar to pair and enable SR-1. Enabling radar switches off camera-based BSD alerts.
Moving one display between two motorcycles
A display pairs with one SR-1 at a time. If each motorcycle has its own radar, moving the display does not automatically switch the radar pairing. Delete the previous radar pairing, then pair the SR-1 on the motorcycle you’re riding.
Where the sound comes from
Enable sound alerts on the compatible display to hear warnings from its built-in speaker. SR-1 alert sounds cannot be sent to a Bluetooth helmet headset, even if the headset is connected to your phone or display.
Choose your activation speed
The available activation speeds are 0, 10, 30 and 50 km/h. See Understand SR-1 alerts and settings for warning light behavior and other settings.
Keep using your mirrors and checking blind spots. Radar is an aid to rider awareness, not a replacement for those checks.
Updates, accessories and certifications
Update without a display
Using SR-1 on its own? You can still update its firmware by connecting it to the CHIGEE GO app.
Optional radar mirrors
CG Radar Rearview Mirrors combine a mirror and warning indicator. They are optional upgrades and are not part of the standard SR-1 kit unless selected at purchase.
Certifications
SR-1 has CE, FCC and waterproof certifications.
FAQs
Can I use SR-1 and CGRC Multi together?
Yes. You can use SR-1 and CGRC Multi together on your CHIGEE Display.
What should I check if alerts stop working?
Start with SR-1 radar not alerting or behaving unexpectedly. It separates power, indicator, display and alert issues so you can check the relevant part first.
