Yes, mine are OEM grips, although those are OEM heated grips and are slightly lighter in color than non-heated. Grey vs. black.
The holes in the ends were meant for bar-end mirrors ages ago, but when I cut out the ends and saw where the wires were for the heating elements, I realized the mirrors would destroy the wires, so they have been like that ever since.
Edit: I just realized you are probably talking about the brush guards.
They, too, are OEM for the G/S and GS models. They are available in black or white.
They are meant to be used on the bikes that have the rectangular brake master cylinder.
I have the round master cylinder, so I had to
butcher the right one to fit.
The left one slides right on.
If you have a rectangular master cylinder, they will easily fit your bike.
