What is this grommet for?

In the pic below you can see a loose rubber grommet around the wire going to the side stand switch (you can also see it in all the pics in the chapter on oil leak). One might think that this grommet should be stuck somewhere protecting the wire. Well, it turns out it is not, this is a superfluous grommet with no purpose whatsoever, probably because the same part is used on another bike where it is needed. Just ignore it. Or cut it and remove it to gain a few grams…

Turns out that Touratech found the grommet useful as their "side stand switch protection" uses it. Here you go.
