The HJC RPHA 91 Carbon Modular Helmet combines a premium Integrated Matrix EVO Carbon shell with a streamlined modular design. Carbon and carbon-glass hybrid reinforcement materials support enhanced shock-resistant performance, lightweight construction, and comfort. Its refined chin bar locking system promotes smooth engagement while helping reduce cheek pressure, and the dual-axis pivot mechanism keeps the chin bar close to the shell to minimize air resistance and wind noise.

A 3D-engineered low-noise interior helps diminish road noise, while the EPS design accommodates eyewear. The helmet provides full front-to-back airflow through five intakes and seven exhausts, with eyebrow vents serving as both ventilation and defogging features. The HJ-37 visor is Pinlock 120XLT prepared, anti-scratch coated, and provides 99% UV protection.

The dynamic multi-step sun visor features a smoke tint and anti-fog coating for clear vision. A bottom-positioned operating system enables quick activation, while the adjustment feature allows the visor to move closer to the face for personalized shading and comfort. The premium-fit interior uses anti-bacterial fabric designed for moisture wicking and quick drying, with 3D-contour cheek pads, reflective material, and interchangeable cheek pads across all sizes.

Removable and washable crown and cheek pads support convenient maintenance. The chin curtain retracts in the open position for easier installation, and the helmet is compatible with second-generation Smart HJC Bluetooth systems.
