HJC C91 Solid Modular Helmet with HJ-17 Shield - DOT Approved, Semi Flat Titanium, X-Large

Rider-focused protection that adapts to your ride

The HJC C91 is built around a lightweight polycarbonate composite shell with a CAD-designed adjustable chin bar. The modular construction lets you open the face shield with one hand while wearing gloves, a practical touch for quick stops and in-town riding. The HJ-17 Pinlock shield adds clear visibility and strong UV protection, while the shield system supports fast, tool-free changes for different light and weather conditions.

Designed for real life on the road, this helmet pairs a secure, comfortable shell with a shield setup that includes an integrated sun visor. You can deploy the visor quickly and smoothly with a single slide, reducing distraction during frequent sun angles or sudden glare.

Comfort and fit that last through long days in the saddle

The interior features a SuperCool moisture-wicking liner that dries quickly, with removable and washable cheek pads. Interchangeable cheek pads across sizes ensure a snug, personalized fit. Glasses wearers benefit from a dedicated glasses groove that minimizes pressure and enhances comfort for eyewear users.

• Double D-ring chin strap provides secure closure and easy adjustment.
• Included pinlock shield, sun visor, breathe deflector, and chin curtain help manage climate and visibility.

Airflow that keeps you cool from stoplight to highway

The ACS Advanced Channeling Ventilation System channels air from front to back, flushing heat and humidity out of the helmet as you ride. The quick-access sun visor plus a robust venting system helps maintain a comfortable feel even on longer stretches.

• Speaker pockets enable optional Bluetooth systems when you choose to add them later.
• Smart HJC Ready compatibility allows you to upgrade with Bluetooth units without swapping helmets.

In short, the C91 pairs a protective, lightweight shell with adaptable features that suit urban commutes and longer journeys alike. The design emphasizes practical maintenance, with a washable interior and easily replaceable components, while keeping the focus on rider comfort and visibility without promising guaranteed results.
