Anyone recognize this?

This was laying on the garage floor after I rolled out several bikes. I feel like the NSR250 was parked near that spot. I would say it is part of the chain slider, but I searched and could not find a missing piece. I did perform the rivet and trim repair to the OE broken slider, but I can't imagine another piece fell off.
Here is the piece. It is hard plastic. There is a "cross member " in the center. Looks like it would slip over something. IDK.

 

Nope. A Honda part made of hard plastic in that shape is low probability, in my opinion. But I haven't disassembled NSRs or NCs either.

The only thing that comes to mind would be like a counter sprocket cover where that slides onto the cases and cover and is then held in place when bolted.

 

Try Google image search?
