FAQs

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

The Premium Integrated Matrix (P.I.M.) Evo shell is a unique construction that integrates a blend of carbon-aramid hybrid and natural fibers. This combination provides enhanced shock-resistant performance while keeping the helmet exceptionally light and comfortable.

How effective is the ventilation system?

The helmet features a full front-to-back airflow system with 2 intake and 4 exhaust vents. This system is designed to channel air efficiently, providing effective cooling and a comfortable riding environment, even in warm conditions.

Is the helmet suitable for all types of riding?

The HJC RPHA 31 is particularly well-suited for urban commuting and motorway riding due to its aerodynamic design and comfort features. While it meets high safety standards, users should consider the specific protection offered by open-face designs for different riding conditions.

What is the benefit of the anti-bacterial fabric?

The advanced anti-bacterial fabric used in the interior lining helps to wick away moisture, dry quickly, and maintain a hygienic environment inside the helmet, contributing to overall rider comfort during long rides.

Does the helmet come with a Pinlock insert?

The HJ-39 visor is Pinlock ready, meaning it has the necessary anchors for a Pinlock insert. However, the Pinlock insert itself is typically sold separately and is required for fog-free vision.

How should I clean the helmet's interior?

The interior liner is removable. It should be hand-washed with mild soap and cold water, then rinsed thoroughly and allowed to air dry completely. Do not machine wash or tumble dry.

What safety certification does this helmet have?

The HJC RPHA 31 Motorcycle Helmet is ECE 22/06 certified, which is a rigorous European safety standard ensuring the helmet meets strict protection and quality criteria.

Troubleshooting

Helmet feels too tight or causes pressure points

The interior padding may take some time to break in. If discomfort persists, consider trying different thickness cheek pads or consulting HJC's sizing guide for potential alternative sizes or liner options.

Wind noise is excessive

Ensure the visor is fully closed and latched. Check that the chin curtain (if equipped) is properly installed. The aerodynamic design aims to reduce noise, but some level is inherent to open-face helmets at higher speeds.

Sun shield is difficult to operate

Ensure the shield mechanism is clean and free of debris. Operate the shield smoothly through its intended range of motion. Refer to the user manual for specific operating instructions.

Fogging on the main visor

The HJ-39 visor is Pinlock-ready. Install a compatible Pinlock insert for optimal anti-fog performance. Ensure adequate ventilation by opening the top or rear vents.

Setup, Compatibility & Care

Initial Setup:

  3. Pinlock Installation: If using a Pinlock insert, carefully follow the Pinlock manufacturer's instructions for installation on the HJ-39 visor.

Compatibility:

  • The HJ-39 visor is Pinlock ready. A Pinlock insert is recommended for fog-free riding in humid or cold conditions.
  • The helmet is designed to accommodate various communication systems, though specific compatibility may vary by brand. Ensure any additions do not compromise the helmet's structural integrity or fit.

Care Instructions:

  • Shell Exterior: Clean the shell with a soft, damp cloth and mild soap. Avoid abrasive cleaners or solvents that could damage the finish.
  • Visor: Clean the visor with a soft cloth and water. For stubborn dirt, use a mild soap solution. Do not use aggressive cleaners.
  • Interior Liner: The interior lining is removable and washable. Hand wash with mild soap and cold water, then rinse thoroughly. Allow it to air dry completely before reinserting. Do not machine wash or tumble dry.
  • Ventilation Ports: Periodically check and clean ventilation ports to ensure unobstructed airflow. Use a soft brush or compressed air.
