Helmet Description

The HJC i91 Bina is a modular (flip-up) helmet designed for touring and everyday riding. It combines the safety of a full-face helmet with the flexibility of an open-face configuration, making it a great choice for riders who commute, tour, or need to interact at stops without removing their helmet. Its aerodynamic shell, internal sun visor, and updated ventilation system make it a versatile and comfortable helmet for long hours on the road.
