Genuine LS2 FF901 Advant X Replacement Interior Kit

Genuine LS2 replacement comfort interior for the standard FF901 Advant X modular helmet. The kit comprises the crown liner and a pair of cheek pads. Select the variant that exactly matches the size marked on your helmet.

Compatibility

• LS2 FF901 Advant X, standard composite-shell version, ECE 22.06
• Available helmet-size variants: XS, S, M, L, XL, XXL and 3XL
• FF901 Advant X shell groups: XS-S-M-L and XL-XXL-3XL
• Each size has its own SKU under manufacturer family reference 800901LNR01.

Important: Match the replacement kit to the exact helmet size rather than choosing only by shell group. This kit is not for the FF901 Advant X Carbon, which uses the separate 801901LNR01 liner family. It is also different from FF900 Valiant II interiors. This listing is for the comfort liner and cheek pads, not the EPS impact liner, outer shell or chin curtain.
