Neither RM-1 version has its own radar. Choose the version that matches your motorcycle and the system that supplies the alerts.

Choose RM-1 for BMW for a BMW R 1300 GS or R 1300 GS Adventure with factory Riding Assistant. Choose RM-1 CG for other motorcycles with M10 screw-in mirror mounts. An R 1300 GS or GS Adventure without factory Riding Assistant is not supported by either version.

The table below shows which RM-1 version fits which motorcycles, where the alerts come from, and what each version can show.

RM-1 CG is available in Angular and Round shapes. Both shapes work the same way with the SR-1 Radar.

The Round shape is the first-generation RM-1 CG. Its indicator light sits lower on the stem and is longer than on the Angular shape. The Round version folds from the base, which is the mounting point, while the Angular version folds from the mirror arm.

RM-1 for BMW and RM-1 CG share the same mirror design and glass. The connection and the alert source are what differ. See the RM-1 for BMW product page and the RM-1 CG product page when you are ready to order.

What you need depends on which RM-1 version fits your motorcycle. A CHIGEE Display already on the bike does not decide which version to buy.

RM-1 for BMW fits all BMW R 1300 GS and R 1300 GS Adventure motorcycles, and it needs factory Riding Assistant to show alerts. If you are not sure whether your motorcycle has Riding Assistant, check its specification or ask your dealer.

To install RM-1 for BMW, see Install RM-1 for BMW on an R 1300 GS or GS Adventure.

RM-1 CG fits motorcycles whose original mirrors screw into M10 mounts with a P1.50 or P1.25 thread. Before you order, check the thread pitch, the thread direction, and the clearance around the mounts. A brand or model name alone is not enough to confirm the fit.

The box includes bolts for P1.50 and P1.25 threads, in right-hand and left-hand versions. Stem lights work only when RM-1 CG is connected to SR-1, which is sold separately. Without SR-1, RM-1 CG works as a regular rearview mirror.

To install RM-1 CG and connect it to SR-1, see Install RM-1 CG mirrors and connect them to SR-1. For SR-1 itself, start with SR-1 radar: compatibility, setup and everyday use.

RM-1 limitations depend on the version and on your motorcycle’s alert system. Neither version detects traffic on its own.

For lab tests and E-mark status, see RM-1 certifications and road use.

Does RM-1 have a built-in radar?

No. Neither RM-1 version detects traffic on its own. RM-1 for BMW displays alerts from factory Riding Assistant, and RM-1 CG displays alerts from the CHIGEE SR-1 Radar.

Do I need SR-1 if I buy RM-1 for BMW?

No. RM-1 for BMW shows alerts from factory Riding Assistant, and it does not connect to SR-1.

Can I use RM-1 CG without SR-1?

Yes. RM-1 CG works as a regular rearview mirror without SR-1, but the stem lights stay off until you connect it to SR-1.

Will RM-1 CG fit a motorcycle that is not a BMW?

It may, if the motorcycle uses compatible M10 screw-in mirror mounts. Check the thread pitch, thread direction, and clearance before you order, or contact us with photos of the mounts.

What if my R 1300 GS or GS Adventure does not have Riding Assistant?

Neither RM-1 version supports an R 1300 GS or R 1300 GS Adventure without factory Riding Assistant. RM-1 for BMW needs that system to show alerts, and RM-1 CG does not fit those motorcycles.

Can the alerts appear on my CHIGEE Display?

With RM-1 CG, alerts can also appear on a compatible AIO-5 or AIO-6 series display through SR-1. RM-1 for BMW shows factory alerts in the mirror stems only and cannot send them to a CHIGEE Display.
