LS2 Advant X Helmet Review: What You Should Know

I kept coming back to the LS2 Advant X helmet review question because this helmet solves a problem that many riders have: getting the freedom of a modular helmet without giving up the feel of a full-face lid. The 180-degree rotating chin bar is the feature that makes it stand out.

After digging into the specs and rider feedback, I found that the Advant X is more than a simple flip-up helmet. It has ECE 22.06 and P/J homologation, a Pinlock Max Vision insert, internal sun visor, removable liner, and a fairly light HPFC shell.

LS2 Advant X Helmet Review: What Makes It Different?

The first thing I noticed about the Advant X is its design. Instead of leaving the chin bar hanging above your head, it rotates all the way to the back.

That sounds like a small detail, but it changes how useful the helmet feels when you stop for fuel, talk to someone, or ride slowly around town.

Feature	What It Means
180° chin bar	Can be used in open or closed mode
HPFC shell	Aims to keep weight down
P/J homologation	Approved for its modular and open configurations

The current LS2 model is the FF901 Advant X. LS2 lists a weight of about 1,600 ± 50 grams and two shell sizes, covering XS through 3XL.

LS2 Advant X Helmet Review: The 180-Degree Chin Bar

This is easily my favorite part of the design.

A normal modular helmet often leaves the chin section sticking up when it is open. The Advant X folds it behind the head instead. That gives the helmet a cleaner balance and makes open riding feel less awkward.

There is still a catch. A moving chin bar means more parts, hinges, and mechanisms than a basic full-face helmet. I would pay close attention to how smoothly it locks and moves when checking a new helmet.

How Comfortable Is the LS2 Advant X?

Comfort looks strong on paper, and rider feedback is generally positive. LS2 uses laser-cut foam, a breathable and hypoallergenic liner, and a removable, washable interior.

The bigger issue is fit. A helmet can have great padding and still feel wrong if its shape does not match your head.

RevZilla’s current feedback shows many riders praising comfort and ease of use, while others report sizing differences and fit problems.

Fit Check	What I Would Look For
Cheeks	Firm but not painful
Forehead	No hard pressure point
Side movement	Very little movement
Chin bar	Should lock firmly

LS2 Advant X Helmet Review: Don’t Guess Your Size

This is one place where I would not take shortcuts.

Measure around your head just above your eyebrows and ears. Then compare that number with the LS2 size chart. RevZilla lists head measurements from 51–52 cm for 2XS up to 65–66 cm for 3XL.

I would also leave the helmet on for several minutes before deciding it fits. A quick try-on can hide pressure spots that become very annoying after an hour.

How Good Is the Advant X on the Road?

The Advant X is built for more than one kind of ride. LS2 specifically describes it as suitable for different riding styles and weather conditions. It has chin and top vents, rear exhaust ports, and channelled EPS to help move air.

That makes it appealing for commuters and touring riders who do not want to own separate helmets for every type of trip.

Riding Type	Advant X Fit
Daily commuting	Very practical
Long touring	Strong option
City riding	Open mode is useful
Aggressive track riding	Not its main role

Ventilation and Hot-Weather Riding

The helmet has a chin vent, top vents, exhaust ports, and a breath deflector. Those features should help air move through the shell.

Still, I would keep expectations realistic.

A modular helmet has more hardware than a simple full-face helmet. In slow traffic on a very hot day, you will still feel the heat. The open chin-bar mode can help when conditions allow it, but that does not replace proper ventilation.

Is the LS2 Advant X Quiet?

This is one of those questions where rider feedback matters more than a spec sheet.

Feedback is generally positive, but it is not perfectly consistent. Some riders praise the helmet’s comfort and quiet operation, while other reviews mention fit and ventilation differences. Carbon versions get particularly good comments about low wind noise.

Your motorcycle also matters. A naked bike and a touring bike can produce very different noise levels inside the same helmet.

Situation	What To Expect
City speeds	Usually manageable
Highway speeds	Earplugs still make sense
Touring screen	May reduce wind blast
Naked motorcycle	More wind noise likely

I would never judge a helmet’s noise level without considering the bike and windscreen together.

What About the Visor and Sun Shield?

The Advant X has a wide anti-scratch main visor, UV protection, a quick-release system, and a built-in drop-down sun visor. LS2 also includes a Pinlock Max Vision 120XLT anti-fog insert.

That combination is very useful for touring. You can move from bright sun to shade without stopping to swap a visor.

The Pinlock is especially useful in cool or wet weather. Fog is one of those small problems that can turn a great ride into an irritating one very quickly.

Visor Feature	Why It Helps
Pinlock Max Vision	Helps reduce fog
Internal sun visor	Handles changing light
UV resistance	Adds protection from sunlight
Wide visor	Gives a broad view

Is the LS2 Advant X Safe?

The current LS2 Advant X carries ECE 22.06 and P/J homologation. It also has a multi-density EPS liner, Emergency Release System, reinforced chin strap, and micrometric metal buckle.

The P/J rating is especially important for a modular helmet. It means the helmet is certified for the relevant closed and open configurations.

Still, certification should not replace fit. A helmet that moves around your head is not something I would accept just because it has a good certification label.

LS2 Advant X Helmet Review: The Safety Detail I Like

The Emergency Release System is a useful feature for a serious crash. It is designed to help emergency personnel remove the helmet more safely.

I also like the reinforced chin strap and metal micrometric buckle. They are simple features, but simple is often good when you need something to work every single time.

What Are the Downsides of the LS2 Advant X?

The Advant X is not perfect. The biggest concern I would have is complexity.

You get a rotating chin bar, sun visor, main visor, vents, locking parts, and modular hardware. That gives you great flexibility, but there are simply more moving parts than on a basic full-face helmet.

Current rider feedback also points to some fit issues, inconsistent ventilation, visor concerns, and variation in build experience.

Possible Issue	Sensible Fix
Poor fit	Try another size or shape
Wind noise	Use motorcycle earplugs
Fog	Use the included Pinlock
Complex mechanism	Check all locks before riding

LS2 Advant X vs a Normal Full-Face Helmet

This is where the buying decision gets easier.

If you want one helmet that can cover commuting, touring, fuel stops, and open-air riding, the Advant X makes a strong case. If you only care about the lightest and simplest full-face design, a normal full-face helmet may make more sense.

The Advant X’s current listed weight is about 1,600 ± 50 grams, which is fairly reasonable for a modular helmet with this much hardware.

Priority	Better Choice
Maximum simplicity	Full-face
Open/closed flexibility	Advant X
Touring convenience	Advant X
Minimum moving parts	Full-face

Is the LS2 Advant X Worth Buying?

After looking at the design, safety rating, equipment, and rider feedback, I think the Advant X is most interesting for riders who actually want modular flexibility.

It is not just a flip-up helmet with a few extras. The rotating chin bar, P/J approval, internal sun visor, Pinlock Max Vision, washable liner, and ventilation system give it a clear purpose.

The main thing I would not compromise on is fit. Rider feedback is positive overall, but fit problems can ruin an otherwise excellent helmet.

LS2 Advant X Helmet Review: Who Is It Best For?

I would look closely at the Advant X if I wanted one helmet for commuting and touring and liked the idea of riding with the chin bar out of the way when conditions allow.

I would look elsewhere if I wanted a very simple, ultra-light race-style helmet or if the Advant X shape did not suit my head.

Rider	My Take
Daily commuter	Excellent match
Tourer	Very good match
Casual city rider	Very practical
Track rider	Look at a dedicated full-face
Fit-sensitive rider	Try before buying

Final Thoughts

My main takeaway from this LS2 Advant X helmet review is that its strength is versatility. The rotating chin bar is not just a gimmick. It changes how you can use the helmet during a normal day of riding.

But I would not buy it based on features alone. Get the size right, test the fit carefully, and make sure the chin-bar mechanism feels solid and natural to operate. If those things work for you, the Advant X is a very interesting modular helmet for everyday riding and touring.
