The HJC i91 Modular Helmet presents itself as a practical choice for riders seeking a balance between comfort, functionality, and affordability. Designed with touring and commuting in mind, this modular helmet offers a range of features tailored to enhance the riding experience.
I wear an HCJ modular helmet often. It’s a lot older helmet than the i91. The i91 takes what previous HJC modular lids offered and kicks things up a notch with excellent improvements all around. This is a great helmet.

Construction and Fit
The i91 features a polycarbonate composite shell, contributing to its lightweight nature. Available in three shell sizes, it accommodates a variety of head shapes, aiming for a snug and secure fit.
The interior is lined with moisture-wicking fabric, and the cheek pads are both removable and washable, facilitating easy maintenance. Eyewear channels are integrated into the design, providing comfort for riders who wear glasses.



Modular Design
The helmet’s modular design allows the chin bar to be lifted, offering convenience during stops or conversations without the need to remove the helmet entirely.
The chin bar locks securely when closed, ensuring safety during rides. It should help in an accident, and it really helps during inclement weather and if you have a bug fly into your face.
Visor System
Equipped with the HJ-33 Pinlock-ready face shield, the i91 provides clear vision and is prepared to handle foggy conditions with the addition of a Pinlock insert (sold separately).
The HJ-V12 internal sun visor is adjustable, allowing riders to manage varying light conditions effectively. This sun visor is noted for its clarity and lack of distortion, enhancing visibility without compromising comfort.
Ventilation
The helmet incorporates a ventilation system designed to promote airflow. However, some users have noted that the ventilation may be less effective in hotter climates, potentially leading to warmer conditions inside the helmet during extended rides.



Noise Levels
While the i91 offers several comfort features, riders have reported that it can be noisier compared to other helmets in its category.
The noise levels are attributed to the visor seal and overall design, which may allow more wind noise to penetrate, especially at higher speeds. If you want a truly quiet helmet, I’d look into other options.
Bluetooth Compatibility
The i91 is compatible with HJC’s SMART Bluetooth communication systems, specifically the 11B, 21B, and 50B models (sold separately).
This integration allows for seamless communication, navigation, and music streaming, enhancing the riding experience for those who prefer connected rides.
Weight Considerations
Weighing approximately 1,720 grams (based on size Medium), the i91 is relatively lightweight for a modular helmet.
However, some riders have noted that the weight can become noticeable during longer rides, potentially leading to neck fatigue.
Final Thoughts for the HJC i91 Modular Helmet
The HJC i91 Modular Helmet offers a blend of comfort, functionality, and affordability, making it a viable option for riders seeking a modular helmet without a premium price tag.
While it excels in areas like visor clarity and Bluetooth compatibility, potential buyers should consider factors such as ventilation efficiency and noise levels based on their specific riding conditions and preferences.
