They are a hard plastic, usually nylon bung that bolts on to your engine. In the case of a slide they should protect your fairings & frame from major damage.
These are mine.
They have a aluminium button and carbon fiber wrapped.
You can get no-cut ones like these that use a mounting plate to offset the slider into your vent. The second option is ones where you drill holes in your fairing and bolt straight on. Some claim the latter to be better as the plate can't bend, although i have never seen a bent mounting plate.
They are a very good investment. People on this forum have had good use fomr theres. I'm sure they will let you know.
