DescriptionThe whole story▼
Genuine LS2 chin bar ratchet system and visor support for the FF906 Advant, part 800906CBR01. This is the detented mechanism that holds the outer visor at each of its open positions, and it also carries the visor's pivot.
It is the part to order when the visor will no longer stay where you put it — when it creeps shut at motorway speed, or drops from the cracked-open position on its own. Riders usually blame the visor itself, which is why they buy a new screen and find nothing has changed. The detents live here, in the ratchet, and they wear before anything else on the helmet does.
Fitted from the outside, with a screwdriver and a few minutes. It carries the visor support, so if the screen has ever been forced past its stops it is worth inspecting this part before assuming the visor is bent.
