Schuberth is reviving the past glory of its C3 helmet with this modular helmet that complies with the drastic new ECE 22.06 regulations, with dual full-face and jet approval. The "Concept 5", which is still in the top-of-the-range modular segment, has been designed to offer sound insulation qualities of no more than 85db(A) at 100Km/h: The sound of silence...Like all touring motorbike helmets, the C5 comes pre-equipped with its own fully integrated kit to accommodate the SC2 communication system, which is completely invisible and plugs in using the Plug'N'Play principle.
