The LS2 Advant X (FF901) is a modular motorcycle helmet with a chin bar that rotates a full 180 degrees to rest behind the head, so the same helmet can be ridden as either a full face or an open face. The shell is high performance fiberglass composite (HPFC) and the helmet weighs 1600 g plus or minus 50 g. It is certified to ECE 22.06, ECE P and J (dual open and full face homologation), and DOT FMVSS 218. Sizes run XS through 3XL across two shell sizes, and every helmet ships with a Pinlock 120XLT MaxVision insert, a dark smoke shield, and a carrying bag.
What this helmet is built for
The Advant X is aimed at riders who want one helmet for mixed use: closed up on the highway, opened up in traffic, at fuel stops, or on slow city miles. Because it carries both the ECE P (protective chin bar) and J (open face) ratings, it is legal to ride in either position rather than only for stopping. The tradeoff for that versatility is weight and cost: at roughly 3 lb 8 oz it is heavier than a comparable full face, and the rotating mechanism adds parts that a fixed-chin helmet does not have.

How to measure for helmet fit
Measuring your head is the right place to start, but it is only a guideline. Different head shapes can require a slightly smaller or larger helmet in any given model, so trying on the specific model is always recommended. A helmet should be as snug as possible without being tight enough to cause a headache. Being fitted in person by a professional is the most reliable method.
Measure the circumference of your head with a tape measure, or with a length of string that you then line up against a ruler.
Start above the ear and circle all the way around, resting the tape about a half inch above the eyebrows and across the fullest part of the back of the head.
Measure several times so you do not end up with a reading that is too small or too large.
Compare your measurement to the size chart. If you fall between two sizes, take the larger size.

Common questions
Can the Advant X be ridden with the chin bar rotated back?
Yes. It carries ECE P certification as a full face and ECE J certification as an open face, which means it is homologated for riding in either position rather than only for stopping.
Does the Advant X come with a Pinlock insert?
Yes. A Pinlock 120XLT MaxVision anti-fog insert is included in the box, along with a dark smoke shield and a carrying bag.
Does it have an internal sun visor?
Yes. A drop-down sunshield is built into the shell and operates from a hidden sliding button. It can be removed without tools using the easy-remove mechanism.
How much does the Advant X weigh?
1600 g plus or minus 50 g, roughly 3 lb 8 oz. That is heavier than a typical fiberglass full face, which is the usual tradeoff for a modular chin bar mechanism.
What size shell will I get?
The Advant X uses two shells. Sizes XS through L share one shell, and XL through 3XL share the other, with five EPS densities and seven liner sizes spread across the range to keep proportions correct.
Can I change the fit without changing helmet size?
To a degree. Cheek pads are available in slim and standard thickness in three size groups, and the liner is sold separately in seven sizes, so the interior can be adjusted within a shell size.
Do Advant X parts fit the standard Advant?
Shields and Pinlock inserts do not. Advant X shields and inserts do not fit the Advant FF906, and Advant KPA shields do not fit the Advant X or Advant X Carbon. The inner drop-down sunshield is the exception and fits Advant, Advant II, Advant X, and Advant X Carbon.
Before You Select a Size: Helmet-Fit Facts
A helmet is one of the most important pieces of riding gear you will choose, and the size printed on the label is only a starting point. Head circumference, head shape, crown contact, cheek-pad pressure and the retention system all affect whether a helmet fits correctly. Two helmets marked the same size can fit very differently—even within the same brand.
Measure around the widest part of your head, keeping the tape level and approximately one inch above your eyebrows.
A new helmet should feel evenly snug around the entire head without sharp or painful pressure points.
When you move the helmet gently from side to side, your skin should move with the liner rather than the helmet sliding independently.
Fasten the retention system and confirm that the helmet cannot roll forward or lift off the head.
Wear the helmet for several minutes before deciding. Comfort padding may settle with use, but an incorrect shell shape or painful pressure point is unlikely to be solved by choosing blindly.
Why Come to Eagle Leather for a Helmet Fitting?
Our staff is trained to help with helmet fitting and can help you compare head shape, size, pressure points and retention across different models. Inventory changes daily, but Eagle Leather consistently carries many hundreds of helmets—often approaching 1,000 units—across half-shell, open-face, modular, adventure and full-face styles. That selection gives you the opportunity to compare brands and internal shapes instead of relying on a size label alone.
For such an important piece of riding gear, we encourage you to visit Eagle Leather for an in-person fitting before selecting a size without trying the helmet on.
