FAQs
Is the Pinlock insert included with the HJC RPHA 91?
The HJC RPHA 91 comes Pinlock-ready, meaning it is designed to accept a Pinlock insert. Whether the insert is included depends on the specific package or retailer; it is often sold separately.
How do I clean the interior liner?
The interior liner is removable. Hand wash it gently with mild soap and cool water. Rinse thoroughly and allow it to air dry completely before placing it back in the helmet. Do not use harsh detergents or machine dry.
Can I install a third-party Bluetooth system?
The RPHA 91 is specifically designed to accommodate the second-generation Smart HJC Bluetooth systems. While it may have space, compatibility with third-party systems is not guaranteed and may require modification.
What makes the P.I.M. Evo shell special?
P.I.M. Evo stands for Premium Integrated Matrix Evo. It's a special construction method using multiple layers of advanced materials, including carbon-aramid, carbon fiber, and natural fibers, to create a shell that is exceptionally strong, offers excellent energy absorption, and is remarkably lightweight.
How does the chin bar locking system work?
The RPHA 91 features a hidden closure point for the chin bar, designed for a smooth contact and reduced pressure on the rider's cheeks. It requires a deliberate action to ensure a secure lock.
Is this helmet suitable for cold weather riding?
While the helmet offers excellent noise reduction and protection, its suitability for extreme cold depends on rider preference and additional gear. The moisture-wicking interior is beneficial in various temperatures, and the secure fit helps minimize drafts.
Troubleshooting
Helmet feels too tight or too loose.
Ensure you have selected the correct size. If it's slightly too tight, the interior may break in over time. If too loose, a larger size may be needed. Check the cheek pads and crown liner for proper seating.
Chin bar does not close smoothly.
Ensure there are no obstructions in the locking mechanism. Check that the helmet is properly aligned when closing. The hidden closure point may require a firm, deliberate action.
Sun visor is difficult to deploy or retract.
Check for any debris or obstructions around the sun visor mechanism. Ensure the lever or slider is being used correctly as per the manual.
Fogging on the main visor.
Ensure the Pinlock-ready visor is clean. If fogging persists, consider installing a Pinlock anti-fog insert, sold separately.
Bluetooth system not pairing.
Refer to the Smart HJC Bluetooth system manual for pairing instructions. Ensure both the helmet and the Bluetooth device are in pairing mode and within range.

- Shell: Clean the exterior shell with a soft, damp cloth. Avoid abrasive cleaners or solvents that could damage the finish.
