The chin bar can be raised using a discreet button underneath the centre of the bar, allowing to convert the helmet into an open face. HJC’s advanced channelling ventilation system (ACS) provides a high level of airflow from front to back to flush heat and humidity, with reduced wind noise. The HJ-33 Pinlock ready shield offers 99% UV protection, with an integrated sun visor for reducing eye strain and improved peripheral vision.

The C91 is designed to seamlessly integrate the Smart HJC 20B and 10B Bluetooth intercom systems, co-developed with Sena for HJC helmets (sold separately). The removable and washable interior is designed to keep your head fresh and moisture-free throughout your ride, with moisture-wicking and anti-bacterial properties. The I90 uses a simple and comfortable ratchet chin strap fastening system.
