HJC Road Helmet I91 Carst
Smooth touring. Road-ready flexibility. All-day comfort.
The HJC i91 Carst is a sleek, feature-packed system helmet designed with touring and cruiser riders in mind. Engineered to transition effortlessly between full-face protection and open-face ventilation, this helmet is certified for both positions with dual P/J homologation—ideal for versatile road adventures.
Built using HJC’s Advanced Polycarbonate Composite Shell, the i91 balances lightweight construction with impact resistance and aerodynamics. Designed with CFD technology, the shell shape has been refined for smoother airflow, greater stability, and reduced rider fatigue at speed.
Inside, the helmet offers a multi-step internal sun visor, a Pinlock-ready clear visor (with insert included), and a moisture-wicking, washable interior that’s glasses-friendly and ready for long-distance comfort. The i91 is also fully Bluetooth-ready, compatible with the latest SMART HJC 2nd Gen systems (sold separately).
Finished in the striking Carst graphic, this helmet delivers performance, protection, and premium styling for your next road trip.
