LS2 Advant X Review

The LS2 Advant X makes the certification-per-dollar argument as loudly as any helmet on this site. It is a full forged-carbon modular that weighs around 1,550 g — lighter than most one-piece full-face helmets, never mind flip-ups — and it carries genuine DOT + ECE 22.06 with P/J homologation, for a price well under the premium tier. The catch is the one every modular pays, and we'll be straight about it.

We haven't crash-tested this helmet. The certification comes from the standards body, the weight and specs from LS2, and the ride impressions are aggregated from owners and published reviews.

Genuine ECE 22.06 P/J — the part that matters

The Advant X is homologated ECE 22.06 with P/J dual homologation, meaning it was impact-tested both with the chin bar closed and open, so riding it flipped up is an approved, tested configuration. That is the current rotational-test standard on the shell plus legal open-face use — the same box the far pricier HJC RPHA 91 ticks, in a much lighter helmet. If you rank a modular by the mark on the shell and the weight on your neck, the Advant X is one of the strongest value cases going.

The weight is the headline

Around 1,550 g in a forged-carbon shell is genuinely exceptional for a flip-up — the mechanism and hinge usually add mass exactly where you feel it most, up high. Owners consistently report the neck-fatigue relief on long days is the thing they notice first, especially stepping down from a ~1,880 g premium modular. Forged carbon (chopped carbon compressed into a matrix, rather than woven sheet) is what lets LS2 hit that number at this price.

The honest trade: noise

Here is the catch. A 180-degree flip mechanism and the seams that come with it make the Advant X louder at highway speedthan a sealed one-piece carbon full-face, and louder than the most refined premium modulars. It is not egregious for a flip-up, but if you are the rider who counts decibels, know that the light shell doesn't buy you silence — a sealed Shoei Neotec 3is quieter, if far heavier and pricier. It also uses a micrometric ratchet strap rather than a Double-D ring, and spreads the whole size range across only two shells, so fit is worth checking against LS2's chart before you buy.

Features and daily use

You still get the touring kit: a drop-down internal sun visor, a Pinlock-ready main shield, and a channel designed around LS2's Cardo-based 4X comms so the intercom integrates rather than bolting on. For a rider who wants the lightest certified flip-up they can get and will run earplugs on the highway anyway, the package is hard to argue with.

Sun visor, comms and everyday use

For a helmet whose headline is weight, the Advant X is well-equipped. It has a drop-down internal sun visor, a Pinlock-ready main shield for fog control, and a comms channel built around LS2's Cardo-based 4X system, so the intercom integrates rather than clamping on. The flip mechanism is a full 180-degree design that swings the chin bar all the way back, and the interior is comfortable and removable. In daily use the forged-carbon weight is what you notice first and most — lifting a helmet this light on and off, and wearing it for hours, is a different experience from a ~1,900 g polycarbonate modular, and it's the reason to buy it.

On value, the Advant X is the standout on this site's core metric: genuine ECE 22.06 P/J, in carbon, at a price well below the premium modulars and only a step above the budget field. The honest counterweight is the wind noise and the two-shell fit — you're trading a little quiet and a little fit precision for a lot of weight saving and the current certification. For a rider who values low weight and the mark on the shell above outright silence, that's an easy trade and a genuinely rare combination at the price. Run earplugs on the highway and the Advant X is one of the smartest-money modulars going — compare it directly with the HJC RPHA 91.

Who should skip it

Riders whose first priority is touring silence and plush finish — the premium modulars earn their price there, and this isn't trying to beat them on quiet. And anyone between shell sizes should try it on, because two shells covering the whole range means fit can be less precise than a helmet with four. But if low weight and genuine ECE 22.06 P/J for the money are what you want, the Advant X is one of the best answers on the market.

Where the Advant X sits in the range

The Advant X occupies a genuinely useful gap in the modular field: it's far lighter and cheaper than the premium touring flip-ups, but it carries the current certification the budget ones don't. Its most direct rival is the HJC RPHA 91, the other value helmet with genuine ECE 22.06 P/J — a near dead heat we settle in Advant X vs RPHA 91, where weight favors the LS2 and independent SHARP data favors the HJC. Against a flagship like the Shoei Neotec 3, the Advant X gives up quiet and finish but takes the certification and the weight — the argument we lay out in Advant X vs Neotec 3.

The bottom line: the Advant X is the modular to buy if you want the lightest helmet that still carries genuine ECE 22.06 P/J, and you're willing to trade a little highway quiet to get it. For the weight-conscious, certification-first rider on a real-world budget, it's one of the most compelling helmets on the market — a carbon flip-up with the right mark on the shell, at a price that undercuts the flagships by a wide margin.
