The LS2 FF908 Strobe II is a practical modular motorcycle helmet designed around everyday versatility. With a 90-degree rotating chin bar, ECE 22.06 P/J homologation, a KPA shell and an integrated sun visor, it is built to cover the needs of riders who commute during the week and head out on longer touring rides at the weekend.
LS2 describes the Strobe II as a modular helmet for commuters and touring riders, combining a comfortable 3D laser-cut interior with a useful twin-visor system and configurable airflow. The current manufacturer specification lists a weight of 1,700 g ±50 g and three shell groups: XS-S, M-L and XL-3XL.
One helmet, two approved riding configurations
The defining feature of the FF908 Strobe II is its 90-degree rotating chin bar. This gives riders the flexibility of a modular design while retaining the protection of a full-face configuration when the chin bar is closed and locked.
Its P/J homologation is particularly important here. The LS2 specification confirms ECE 22.06 approval for both approved configurations, so riders can use the helmet in the authorised full-face or open-face position in accordance with the manufacturer's instructions.
KPA shell and multi-density EPS construction
LS2 uses a KPA shell for the Strobe II, backed by a multi-density EPS liner. The helmet also features a reinforced chin strap and a dedicated chin-bar locking system. A micrometric buckle provides quick and straightforward fastening for daily riding.
The manufacturer lists three shell groups — XS-S, M-L and XL-3XL — helping the Strobe II maintain a more proportionate shell structure across its size range. The current listed weight is 1,700 g ±50 g, although actual weight varies with size and configuration.
Clear visor and integrated sun visor
The Strobe II uses a scratch-resistant, UV-resistant outer visor with a quick-release system. LS2 also lists the visor as ready for a Pinlock 70 MaxVision anti-fog insert, while the internal drop-down sun visor provides a convenient way to manage changing light conditions.
For riders who spend long hours on the road, the twin-visor arrangement is useful for moving between bright daylight, shaded roads and lower-light conditions without needing to stop and change the main visor.
Ventilation for everyday riding
Airflow is handled through chin and top vents, supported by a rear exhaust port and channelled EPS. LS2 also specifies a breath deflector to help manage airflow around the visor area.
Comfort-focused interior
The interior is designed for regular use, with 3D laser-cut foam, a breathable and hypoallergenic liner, an elastic-strap top-liner arrangement and removable, washable components. These features make the Strobe II well suited to riders who use their helmet frequently for commuting or longer journeys.
LS2 also lists the FF908 Strobe II as ready for its dedicated intercom system, making it possible to add compatible communication equipment without choosing a different helmet.

Who is the Strobe II designed for?
The FF908 Strobe II makes sense for riders who want one helmet to cover a broad mix of riding. Its modular mechanism is useful in urban environments, while the P/J approval, integrated sun visor, ventilation system and touring-friendly comfort features also suit longer road journeys.
The design is particularly practical for riders who regularly switch between stop-start town riding and open-road miles. The ability to raise the chin bar when permitted gives the helmet added convenience without moving away from a proper full-face configuration when protection and enclosure are the priority.
