The LS2 FF901 Advant X is a flip-up touring helmet with a 6K carbon shell and a chin bar that rotates 180 degrees to the back, turning it into an open-face helmet. It carries ECE 22.06 and P/J homologation, so it is approved for riding both ways. The kit is generous for a carbon modular: Pinlock 120XLT MaxVision insert, a dark visor, drop-down sun visor, emergency release cheek pads and a washable X-Static silver liner. At around 1550 g it is light for a modular, though still heavier than a plain full-face. It suits touring and commuting riders who want one helmet for both modes and accept the extra weight and mechanism over a fixed full-face.

Owners of the Advant X line praise the light carbon build, the wide field of view and the included Pinlock and dark visor. Complaints center on wind noise at highway speed and on the flip mechanism feeling stiff when new.
The LS2 FF901 Advant X Forged Gloss Carbon is a convertible helmet. It has a carbon shell and a carbon chin bar that rotates 180 degrees.
The liner is multi-density EPS with channelled interior, laser-cut foam and a removable, washable X-Static© silver liner fabric. The helmet has a reinforced chin strap, a micrometric metal buckle and an emergency release system. Chin and top vents feed air through the interior, and there is an exhaust port and a breath deflector.
The twin visor system includes a drop-down sun visor. A Pinlock® 120XLT MaxVision™ insert is included, and a dark visor comes in the box. The helmet is compatible with LS2 INTERCOM, which must be installed with adhesive only.
