The SR-1 Millimeter-wave Radar System helps riders improve rear awareness by detecting approaching vehicles from behind and providing clear visual warning alerts.
This guide explains how SR-1 works, what motorcycles it fits, what’s included in the standard kit, which CHIGEE displays are compatible, and what to know before installation.
Before You Buy
SR-1 can be used in two ways:
Standalone Mode: Use SR-1 with the included external indicator lights. No CHIGEE Display is required.
Display Integration Mode: Pair SR-1 with a compatible CHIGEE Display for on-screen radar graphics, sound alerts, and radar settings.
Motorcycle Compatibility
SR-1 is designed to work with most motorcycles that use a standard 12V electrical system.
It can be installed on a wide range of motorcycle types, including:
Adventure bikes
Sport bikes
Cruisers
Touring motorcycles
Naked bikes
Commuter motorcycles
SR-1 does not require proprietary motorcycle connectors, a model-specific harness, or permanent modification to your bike. In most cases, installation only requires mounting the radar module at the rear of the motorcycle, installing the warning lights, and connecting the wiring harness to the motorcycle’s power system.
What’s Included in the Standard SR-1 Kit?
The standard SR-1 kit includes the main components needed for standalone radar warning operation:
SR-1 radar module
Two standalone indicator lights
Required wiring and mounting accessories
The included indicator lights provide the core visual warning function. They are designed to be installed without replacing your existing motorcycle mirrors or display system.
Can SR-1 Work Without a CHIGEE Display?
Yes. SR-1 can be used independently without a CHIGEE Display.
In standalone mode, the radar module detects approaching vehicles from behind and sends alerts through the included flashing indicator lights. This provides the basic SR-1 warning function without requiring screen integration.
Standalone mode is suitable for riders who want radar-based visual alerts but do not use a CHIGEE display.
Using SR-1 with a CHIGEE Display
SR-1 can be paired with compatible CHIGEE Displays to show radar alerts directly on the screen. You can also access radar settings from the display menu and enable audible alerts through the display speaker.
When SR-1 is connected to a compatible CHIGEE Display, installing the included amber light strips is optional. The radar can work normally with the display alone, and alerts will appear on the screen.
The amber light strips are mainly for standalone use without a CHIGEE Display, or for riders who want an additional visual alert.
Visual Alerts and Sound Alerts
The SR-1 radar module and indicator lights provide visual warnings only. They do not produce sound alerts on their own.
To receive audible radar alerts, you must pair SR-1 with a compatible CHIGEE Display and enable Sound Alerts in the display settings.
Bluetooth Headset Limitation Radar alert sounds cannot be transmitted to a Bluetooth headset. Even if your phone or CHIGEE display is connected to a Bluetooth headset, SR-1 radar alert sounds will only play through the CHIGEE display’s built-in speaker.
Optional Upgrade: CG Radar Rearview Mirrors
The CG Radar Rearview Mirrors are optional upgrades for SR-1.
They combine the rearview mirror and radar warning indicator into one integrated setup, helping keep the cockpit cleaner while still providing visual radar alerts.
These mirrors are not included in the standard SR-1 package unless specifically selected at purchase.
Basic Installation Guide
SR-1 installation includes three main steps:
1. Radar Module Installation Mount the radar module at the rear of the motorcycle. Make sure it is securely fixed, facing backward, and not blocked by luggage, body panels, license plate holders, or other accessories.
2. Warning Light Installation Install the two warning lights where they are clearly visible to the rider. They can be attached to the original rearview mirrors or installed with the optional M10 warning light brackets.
Note: If you use SR-1 with a compatible CHIGEE Display, you can choose to use the radar module with the display only, without installing the external warning lights. The system will still provide radar alerts through the display.
3. Product Wiring Connect the SR-1 wiring harness according to the wiring diagram in the user manual. After wiring is complete, power on the system and check that the warning lights work normally.
For riders who would like a visual reference during installation, YouTuber AdvExplorerOz has created a video that includes helpful sections showing the SR-1 installation process.

Installatie was simpel: gewoon in het dock klikken en CarPlay verbinden. Wonder Wheel werkte zonder problemen. Het display is wat klein, maar wel helder en scherp. Een groter display zou mij overtuigen om te upgraden, maar verder ben ik tevreden.

Bmw s1000xr k49 2015: de voorste druksensor met de kortere ventiel heeft een maximale afstand van 2 mm tot de remklauw. Ik heb het afgerond om de veiligheid te verhogen. Het zou goed zijn om een interne sensor te maken zoals de BMW Schrader.
Bedankt voor uw gedetailleerde feedback.
Het spijt ons dat de externe TPMS-sensor niet volledig aan uw verwachtingen voldeed op uw BMW S1000XR 2015.
Onze externe TPMS-sensoren zijn ontworpen om op de meeste motorwielen te passen, maar zijn niet specifiek ontwikkeld voor elk BMW-model. Bij sommige motoren is de ruimte tussen het ventiel en de remklauw erg beperkt, zoals in uw geval.
Als de vrije ruimte slechts ongeveer 2 mm is, raden we aan zeer voorzichtig te zijn en geen externe sensor te gebruiken als u het risico op contact met de remklauw tijdens het rijden voelt.
We begrijpen ook uw suggestie voor een interne sensor vergelijkbaar met het BMW Schrader-systeem. Wij bieden interne TPMS-sensoren als alternatief, die u kunt overwegen als u een discretere installatie en meer ruimte voor dit type wielopstelling wenst.
Een krachtig systeem. Ik vind het jammer dat de kabels van de rechte en linker LED's iets te kort zijn. Ik denk dat u verlengstukken zou moeten aanbieden.
