FAQs
How do I clean the interior of the HJC RPHA 91 helmet?
The interior lining is typically removable. Hand wash the pads with mild soap and cool water. Rinse thoroughly and allow them to air dry completely before reassembling the helmet. Do not use harsh detergents or machine wash.
What is the warranty period for the HJC RPHA 91?
HJC helmets usually come with a manufacturer's warranty, typically covering defects in materials and workmanship for a specified period, often two years from the date of purchase. Please refer to the warranty documentation included with your helmet for exact terms and conditions.
Can I replace the standard HJ-37 face shield with a tinted or mirrored one?
Yes, HJC offers various replacement visors for the RPHA 91, including tinted, mirrored, and electric options. Ensure you purchase a visor specifically designed for the RPHA 91 model to guarantee compatibility.
Is the HJC RPHA 91 ECE or DOT certified?
The HJC RPHA 91 is designed to meet or exceed safety standards. Depending on the region of sale, it will be certified to relevant standards such as ECE 22.06 or DOT FMVSS 218.
How does the chin bar locking system work?
The chin bar is secured with a locking mechanism that engages when the bar is lifted and closed. It is designed with a hidden closure point for a smooth feel and reduced pressure on the rider's cheeks, providing a secure closure when riding.
What makes the P.I.M. Evo shell different from standard helmet shells?
The P.I.M. Evo shell uses a blend of advanced composite materials, including carbon-aramid, carbon fiber, and fiberglass, along with organic non-woven fabric and linen fiber. This combination enhances shock-resistant performance while keeping the helmet exceptionally lightweight.
Can I install a communication system on this helmet?
Yes, the RPHA 91 is specifically prepared to accommodate the second-generation Smart HJC Bluetooth systems. Installation instructions will be provided with the Bluetooth communication system itself.
Troubleshooting
Helmet feels too tight or causes pressure points.
Check if the helmet size is correct. If the helmet is the correct size, the interior padding may need a break-in period. For persistent issues, consider aftermarket thinner or thicker cheek pads or crown liners available for the RPHA 91.
Visor fogs up despite Pinlock readiness.
Ensure the Pinlock insert is correctly installed and sealed against the main visor. Check that the vents are open to allow airflow. Clean both the main visor and Pinlock insert as they can become less effective if dirty.
Chin bar does not lock securely.
Inspect the chin bar locking mechanism for any debris or obstructions. Ensure the chin bar is fully closed until it clicks into place. If the issue persists, contact customer support or a qualified dealer.
Sun visor is difficult to operate.
Verify that the helmet's main visor is fully opened or closed, as some mechanisms require this for smooth sun visor operation. Check the sun visor's track for any debris. Ensure the 3-step adjustment slider is clean and functioning.
Wind noise is still noticeable.
Ensure the neck roll and cheek pads are properly installed and making a good seal. Check that the chin curtain (if equipped) is in place. Riding posture and motorcycle fairing design can also influence perceived wind noise.

Setup, Compatibility & Care
Setup:
- Initial Fit Check: Ensure the helmet fits snugly but comfortably. The interior padding should offer a consistent pressure without any specific tight spots.
- Visor Adjustment: The main HJ-37 face shield and HJ-V17 sun shield should operate smoothly. Check that the locking mechanism for the chin bar is secure when closed.
- Eyewear Insertion: If wearing glasses, gently slide them into the designated channels within the EPS liner. Adjust their position for comfort before closing the chin bar.
- Bluetooth Integration: If installing the Smart HJC Bluetooth system, follow the specific instructions provided with that accessory for mounting and pairing.
Compatibility:
- Eyewear: Designed to accommodate most standard eyeglasses. Fit may vary with very large or unusually shaped frames.
- Bluetooth Systems: Compatible with the second-generation Smart HJC Bluetooth communication systems.
- Aftermarket Accessories: While modifications are generally not recommended for safety reasons, ensure any aftermarket visors or accessories are specifically designed for the RPHA 91 model.
Care:
- Exterior Shell: Clean the P.I.M. Evo shell with a soft, damp cloth. Avoid using abrasive cleaners or solvents, which can damage the finish and protective layers.
- Interior Lining: The moisture-wicking and quick-drying interior lining is typically removable. Refer to the helmet's manual for specific instructions on removing and hand-washing the pads with mild soap and cool water. Allow them to air dry completely before reinserting.
- Visors: Clean the HJ-37 face shield and HJ-V17 sun shield with a soft cloth and a mild, non-abrasive cleaner or a dedicated visor cleaner. Do not use paper towels, which can cause scratches.
- Storage: Store the helmet in its protective bag in a cool, dry place away from direct sunlight to prevent material degradation.
