The AGV K1-S is a full-face sport helmet that carries design and aerodynamics work from AGV's MotoGP program into a road-ready shell. It uses a high-resistance thermoplastic resin shell with a multi-density EPS liner, a wide Ultravision visor that is Pinlock-ready, and a wind-tunnel-shaped aero spoiler for stability at speed. It suits riders who want a race-styled helmet for sport and everyday road use, and it sits below AGV's carbon and fiberglass models on materials while keeping the racing shape and ventilation layout. Owners rate it highly, and the recurring themes are its light weight, quiet ride and strong value against premium AGV lids.
