Best LS2 Advantage X carbon motorcycle helmets

Top pick: LS2 Advant X Carbon — it's the helmet you asked for, and the one to buy if you want a flip-up you can ride with the chin bar up at a light and closed on the highway. The 9K carbon shell comes in two shell sizes (XS–LG and XL–3XL) with an intermediate-oval fit, and the chin bar swings a full 180°, so it sits behind the head instead of catching wind.

Who the others suit:

• LS2 FF901 Advant X Solid Carbon — same flip-up idea, plain carbon finish, if you'd rather not have a graphic.
• LS2 Advant X Carbon Future II / Halo — the Future II is the graphic version; the Halo adds a Pinlock insert in the box, worth it if you ride in cold or rain.
• LS2 Thunder Carbon — fixed full-face, lighter-feeling and simpler, for riders who never flip the front up.
• HJC F71 Carbon — a fixed full-face from a big-name brand if you want a different fit shape.
• Nolan X-804 RS Ultra Carbon — the premium fixed full-face choice, best-rated of the group.
• Nexx X.R3R Zero Pro 2 Carbon — sport-touring fixed full-face with ECE 22-06.
• ILM 861C — budget carbon-look full-face, DOT and ECE.

Fit matters more than the shell: try the size you'd buy, and remember a flip-up is heavier than a fixed full-face of the same shell.
