Rear Wheel Speed Sensor Housing Damage

Please see photo. Any idea what could have cause this damage? Thanks for the input!

How about posting a picture of the brake caliper ?

I’ve seen this plenty of times. I’m not standing next to your bike but here are a few ideas: It looks like the ABS sensor disc might be in the wrong location. The washer was put on the wrong side. Rear wheel bearing is failing. Problem with rear pads or piston. It’s hitting the pad or the brake carriage. Possibly the axle was installed in a funky order and did not pull that over into the proper location (doubtful). It’s probably one of these type things.

Once in a million years a rock gets jammed and will do this but I have found it rare

The damage is cosmetic, but you do need to got through Jaxon's list. Something got done wrong with the last tire change. Oh, the abs sensor screw is falling out if you didn't notice.

If it were rock damage, it would likely be less uniform. I think mine has some random hits.

Thank you. Will be removing my rear wheel now and checking everything against a years old post regarding rear wheel replacement. I believe it is the ABS sensor disc. Thank you everyone for your post!

The only thing even close to that plate is the caliper bracket and it's more than 1/8" away. Whatever is rubbing on it should be easy to see.

Possibly the outer brake pad is out of whack and it is hitting the top of the raised ridges.

This next comment doesn’t pertain to your circumstances but you never know what the heck might be going on.

I recently took a look at a friends Tenere. The rear brake pad ‘anti noise’ plate had fallen off only on one side. This allowed that plate to fall down on one side and rest on the hub. It then proceeded to “mill” a ridge into the rear hub. I warned the owner to keep an eye on that hub for cracks. (Everyone should eyeball this plate once and awhile) a compromised hub is not good.
Ya just never know. I see crazy stuff all the time.

The sensor mounting disc has no doings with that ring. That ring is a decorative plate used as part of what bolts the rotor to the hub. The sensor mounting disc is also the spacer that loads the bearing. It's something outside that, seems most likely the washer got installed in the wrong order. But it should be a visual thing to see what has contacted that disc.
