FAQs
What makes the P.I.M. Evo shell superior?
The P.I.M. Evo shell uses an advanced composite weave including carbon-aramid, carbon fibre, and natural fibres. This combination creates an extremely strong yet lightweight structure, enhancing shock absorption and rider comfort by reducing weight.
Is the helmet suitable for riding in cold weather?
Yes, the helmet is designed for all-season comfort. The low-noise interior and neck roll help reduce wind chill, and it is compatible with anti-fog solutions like Pinlock inserts for clear vision in cold and damp conditions.
How do I clean the interior liner?
The interior liner is removable. Hand wash it gently with cool water and mild soap. It should be allowed to air dry completely before being put back into the helmet.
Can I install a communication system from a brand other than HJC?
The RPHA 91 is specifically designed to accommodate the second-generation Smart HJC Bluetooth systems. While some universal systems might be adaptable, full integration and optimal fit are best achieved with the HJC-specific system.
What is the main advantage of the chin bar locking system?
The chin bar locking system on the RPHA 91 features a hidden closure point. This design ensures smoother contact with the rider's face and reduces pressure on the cheek area, enhancing comfort, especially during prolonged use.
Does the helmet come with a Pinlock insert?
The helmet is Pinlock-ready, meaning it is equipped to accept a Pinlock insert. However, the Pinlock insert itself is typically sold separately. Please check the product packaging or listing for confirmation.
How does the helmet help reduce road noise?
The helmet features a 3D-engineered interior specifically designed to minimize road noise. This includes acoustic baffling and a neck roll system that work together to create a quieter riding environment.
Troubleshooting
Helmet feels too tight or loose
Ensure you have selected the correct size by measuring your head circumference according to HJC's sizing chart. Minor adjustments can sometimes be made with thicker or thinner cheek pads, available separately.
Visor fogs up easily
Ensure the Pinlock-ready face shield is properly installed with a Pinlock insert. If not using a Pinlock, use a dedicated anti-fog spray or wipe, and ensure adequate ventilation is open.
Chin bar does not lock securely
Check for any obstructions in the locking mechanism. Ensure the chin bar is fully raised and then firmly pushed down until it clicks into place. If the issue persists, contact customer support.
Difficulty operating the sun visor
Ensure your hand is properly positioned on the slider or lever for the HJ-V17 sun shield. Check that there are no obstructions preventing its movement. Clean the mechanism if it feels stiff.
Bluetooth system not pairing
Refer to the Smart HJC Bluetooth system's user manual for pairing instructions. Ensure both the helmet and the Bluetooth device are charged and within range, and follow the reset procedures if necessary.
