Official Bell replacement rubber edge moulding, supplied in one metre length, that conforms to the same safety standards as those on the original helmets. This moulding rubber isĀ used along the bottom edge of the helmet as well as on visor apertures which are fitted with Eyeport Foam Tape. More recentĀ helmet models which do not use any Eyeport Foam Tape use a different type of rubber moulding.
