The LS2 FF901 Advant X Spectrum motorcycle helmet is a flip-front motorcycle helmet with dual P/J homologation for riding in open-face jet styling or full-face mode. It boasts a highly durable yet lightweight (1550 g) HPFC High-Performance Fibreglass Composite shell, a blend of layers of fibreglass fabric and unique resin, creating an ultralight and rigid shell with two shell sizes for enhanced aerodynamics. A channelled multi-density EPS liner provides excellent impact protection, but also airflow along with LS2's ventilation system with intakes and outlets allows for excellent air circulation. It can be closed for a personalised fit. The modular mechanism is simple to use with a practical chin guard with 180o oscillation. Raising or lowering the chin guard also raises or lowers the visor automatically. The visor is a clear class A screen made of special polycarbonate optically corrected for 3D vision. It has an anti-scratch treatment and UV protection and is Pinlock Max Vision (included) ready. The visor offers a quick-release mechanism for easy replacement, and the interior sun visor is easy to operate while wearing gloves from the outside of the helmet. The FF901 Advent X interior is fully washable, removable, and laser-cut for optimum comfort. It also features LS2's Emergency Extraction System for optimum protection in the event of an impact. Reflective detailing maximises night visibility, and the adjustable micrometric closure with reinforced strap offers a personalised and secure closure.
