The LS2 FF901 Advant X Carbon is LS2's carbon modular, with a chin bar that rotates 180° and dual P/J homologation, at €469 RRP. It is the most sensible way to get a carbon modular without paying premium-brand prices; it gives up some refinement on noise (103 dB) and visor finish compared with a Shoei or a Schuberth. Score: 8/10.
6K carbon shell and 1,550 g
The shell and the chin bar are 100% 6K carbon fibre, not a carbon-look or a mixed composite. It is built in 2 shell sizes (XS to L and XL to 3XL) covering sizes from 53 to 66 cm. The official weight is 1,550 g ± 50 g, and independent scales are close: ChampionHelmets weighed 1,553 g in size M, while Bennetts BikeSocial measured 1,650 g in size L, the largest size on the small shell. For a modular with a flip-over chin bar and a sun visor this is light: the Shoei Neotec 3, our reference modular, weighs 1,732 g.
The 180° chin bar and P/J homologation
This is what sets it apart from a conventional flip-up. The chin bar does not stop above the forehead: it rotates 180° and locks behind the shell, so in open-face mode the weight stays balanced and there is no chin bar catching the wind. That is why it carries dual P/J homologation under ECE 22.06: it is certified to be ridden both as a full-face and as an open-face helmet. Bennetts rates the mechanism as the best thing about the helmet — easy to use with gloves and no jamming during their test — and ChampionHelmets notes that closing the chin bar pulls the visor tight against the shell, which helps with noise.
Visor and sun visor
The Twin Visor System combines a scratch- and UV-resistant clear visor with a quick-release system and an integrated drop-down sun visor. The box includes a Pinlock 120 XLT MaxVision insert and a second dark tinted visor, extras that many rivals charge for. Not everything is perfect: Bennetts found that the visor squeaks when opened and that the seal at the nose wore out after long use with the chin bar open.
Ventilation, interior and noise
Ventilation includes chin and top vents, a rear exhaust, channelled multi-density EPS and a breath deflector. The chin vent only has two positions (open or closed), but both independent tests rate the airflow as good. The liner is X-Static silver fabric, antibacterial, hypoallergenic, removable and washable, with laser-cut foam, an emergency release system for the cheek pads and speaker pockets for LS2's 4X intercom (fitted with adhesive only). On noise the reviews disagree: ChampionHelmets measured 103 dB at motorway speed, not a quiet figure, while Bennetts reported no notable wind noise. As usual with modulars, don't expect the silence of a good full-face. The fit is snug at the cheeks when new, Bennetts needed around 10 hours for it to bed in.
Price: €469 RRP
LS2's official RRP is €469 for solid colours (gloss or matt carbon) and €499 for graphics (Future II, Horizon). As it is not a new model, it is often discounted: in Spain the Future II can be found for around €350 (Motorecambios V. Ferrer), and in Europe the solid versions range between €350 and €420. The fibreglass-composite Advant X is €399, so the carbon version costs only €70 more, a gap that is easy to justify for a helmet you carry on your head for hours.
Pros and cons
Pros
- Real carbon for under €500: shell and chin bar, 1,550 g, well below premium carbon modulars.
- 180° chin bar with P/J homologation: a genuine open-face mode, balanced and certified.
- Complete box: Pinlock 120, sun visor and dark visor included.
Cons
- Noise: 103 dB in the ChampionHelmets test: high.
- Visor: squeaks when opened and the nose seal can wear out.
- Only 2 shell sizes: on the smallest and largest sizes the helmet looks bulkier than a dedicated shell.
Verdict
The LS2 FF901 Advant X Carbon is the most sensible way to get a carbon modular without paying premium-brand prices. The 180° chin bar with P/J homologation makes it truly versatile for touring and city riding, and the box brings everything you need. It gives up some refinement on noise and visor finish compared with a Shoei or Schuberth, but for less than half the price.
Score: 8/10
