Genuine LS2 chin air vent in matt black for the FF902 Scope II, part 806902AVC11, in the ECE 22.06 specification.
This is the vent that clears a misted visor, and it is worth knowing why the top vents do not. Fog forms when the inner face of the visor drops below the dew point of your breath; the chin intake aims outside air directly at that face and raises its temperature. Opening the crown vent cools your head and does almost nothing for the screen. If your visor mists at traffic lights, this is the part that should be working.
It sits on the chin bar itself, which means it moves every time the helmet is opened and takes more handling than any other vent on the shell — the reason it is the one most often broken. Clips in from the outside, one part number for all seven sizes.
