Lightweight Aerodynamic Design for Sport Performance

The HJC RPHA 72 Ernem is a premium sport helmet engineered with the second generation of HJC's Premium Integrated Matrix (PIM) technology. This advanced shell construction uses high-performance fibres infused with epoxy resin to deliver a lightweight profile without compromising structural integrity or impact protection. Designed and wind-tunnel tested for stability at high speeds, this helmet offers a refined balance of safety and comfort for all-season road riding.

Key Features

• Premium Integrated Matrix: Utilises an organised laminate structure of specialised fibre tissues for enhanced durability and uniform stability.
• Advanced Channelling Ventilation: Features a full front-to-back airflow system with dual intakes and exhausts to flush out heat and humidity.
• HJ-48 Shield: Provides 99% UV protection and features an anti-scratch coating with a secure push-release locking mechanism.

Aerodynamics and Visibility

The shell of the RPHA 72 is sculpted through extensive wind-tunnel testing to reduce air resistance and minimise lift, providing a stable platform during spirited sport riding. Visibility is prioritised through the inclusion of a Pinlock®-ready visor and a distortion-free internal sun shield, ensuring clear sightlines in varying light conditions. The visor mechanism operates with a smooth ratchet movement, improving the seal against the shell to reduce wind noise and prevent water ingress.
