Aerodynamics I believe. Prevents lift.

The spoilers are there mainly for single seater racing, to aid the flow of air into the air box behind the head.

about 130mph. I think there's more need for the spoilers though because our heads don't have any bodywork or anything surrounding them.

Theoretically the spoiler as well as the crown ridges (on the helmets that have them) reduce buffeting in rough air and as you move out of the draft into clean air when you reach high enough speeds to actually draft.
