LS2 Helmets Advant X Modular Helmet Review

I’ve tested a lot of modular helmets over the years, and I’ll be honest: the LS2 Advant X genuinely surprised me. After spending proper seat time with it — highway speeds, slow traffic, hot days, and longer rides — this helmet feels like LS2 set out to fix the usual modular helmet frustrations instead of just adding features for marketing.

The flip-around chin bar is the star of the show. In my opinion, it completely changes how usable a modular helmet can be. Unlike traditional flip-ups that catch air and yank your head back, this one rolls smoothly all the way to the rear.

Key Features:

  • 180-degree flip-around modular chin bar
  • Optically correct, scratch- and UV-resistant face shield
  • Removable, washable technical fabric liner
  • Weight around 1,600g (+/- 50g), light for a modular

At speed, it stays stable, balanced, and aerodynamic. I actually enjoyed riding with the chin bar up, not just at stops but on slower roads too.

Comfort was another big win for me. The liner feels premium, soft, and breathable, and after a short break-in period, the fit became spot on. Ventilation works — and I mean actually works — not just on paper.

Final Verdict

After riding with the LS2 Advant X, I understand why so many riders end up loyal to the brand. It’s comfortable, versatile, cleverly designed, and genuinely enjoyable to live with day to day. In my opinion, if you want a quiet modular helmet that actually works while riding — not just while stopped — this one deserves a serious look.

9.5
Our Score

Pros

  • Excellent aerodynamics with the chin bar flipped back: This is where the Advant X really shines. No sail effect, no head pull, even at motorway speeds.
  • Comfort and padding quality: In my experience, the liner feels as good as helmets costing significantly more. After a couple of rides, pressure points disappeared.
  • Good ventilation: I could clearly feel airflow changes when opening or closing vents, especially the chin vent.

Cons

  • Chin strap takes getting used to: Personally, I still prefer double D-rings. The ratchet system works fine, but fastening it blindly isn’t intuitive at first.
  • Not the quietest at high speeds: In my opinion, it’s quiet for a modular, but at 65+ mph, earplugs are still a good idea.
  • Slightly bulky look: On some head shapes, it can appear a bit wide, especially compared to slimmer full-face helmets.
