FAQs

What makes the P.I.M. Evo shell special?

The P.I.M. Evo shell integrates a unique blend of carbon-aramid hybrid and natural fiber materials. This composition provides superior shock-resistant performance, enhancing protection while maintaining a lightweight feel for increased comfort.

How does the airflow system work?

The system features 2 intake vents at the front and 4 exhaust vents at the rear. This configuration creates a pathway for air to flow through the helmet, effectively cooling the rider and removing heat and moisture.

Is the visor compatible with anti-fog inserts?

Yes, the HJ-39 visor is Pinlock ready, meaning it is designed to accept a Pinlock anti-fog insert for enhanced visibility in cold or humid conditions.

How do I adjust the internal sun shield?

The light smoke sun shield features an adjustable 3-step positioning system. You can adjust its position using the integrated control mechanism, typically located on the side or top of the helmet.

What does ECE 22/06 certification mean?

ECE 22/06 is the latest European safety standard for motorcycle helmets. It signifies that the helmet has undergone rigorous testing and meets stringent requirements for impact absorption, penetration resistance, and structural integrity, ensuring a high level of protection.

Can I wash the helmet interior?

The interior lining is made with advanced anti-bacteria fabric and is often designed to be removable. You can typically hand wash the removable parts with mild soap and water. Always allow them to air dry completely before reassembling.

What types of riding is this helmet best suited for?

The HJC RPHA 31 is ideal for urban riders and those who undertake motorway tours. Its features like aerodynamic stability, effective ventilation, and integrated sun shield make it versatile for various riding conditions.

Troubleshooting

Helmet feels too tight or loose.

Ensure you have selected the correct size. If the fit is still not ideal, consider trying different sized cheek pads or liners if available for your model, or consult with a dealer for fitting advice.

Visor fogs up significantly.

Ensure the Pinlock insert (if applicable) is correctly installed and that the visor is properly sealed. Use the helmet's ventilation system to improve airflow. For non-Pinlock use, consider using an anti-fog spray or wipe.

Sun shield is difficult to adjust.

Ensure the mechanism is clean and free of debris. Try operating the adjustment lever slowly and deliberately. Refer to the user manual for the correct operation.

Ventilation seems poor.

Check that all ventilation ports are open and free from obstruction. Ensure the interior lining is clean and dry, as a saturated liner can impede airflow.
