The HJC RPHA 31 Dereen motorcycle helmet offers advanced protection and aerodynamic performance with its PIM Evo shell and multi-density EPS construction. Designed for riders seeking enhanced shock resistance and a quiet, streamlined ride, this helmet incorporates meticulous wind tunnel testing to optimize airflow and reduce turbulence. The integrated sun visor, equipped with anti-fog and smoke-tinted coating, deploys swiftly via a bottom-mounted mechanism, providing effortless sun protection and clarity in varying conditions. The helmet’s aerodynamic shell design, combined with strategically placed air intakes and exhausts, ensures stability at high speeds while minimizing air resistance.
Inside, the RPHA 31 features the premium HJC fit interior made from advanced anti-bacterial, moisture-wicking fabric that dries quickly and maintains comfort during extended rides. The crown and cheek pads are removable, washable, and designed with 3D contouring for a customizable fit, while reflective materials enhance visibility for safety. The helmet is compatible with second-generation SMART HJC Bluetooth communication systems, allowing riders to stay connected without distraction (sold separately). The PIM EVO shell, reinforced with a Carbon-Aramid Hybrid and Natural Fiber, offers superior shock absorption and durability. Additional features include a shield holder that reduces noise and drag, and a multi-step sun visor adjustment to customize shading, providing up to 10 mm of closer positioning for a personalized experience.
This helmet is lightweight, weighing approximately 0.16 pounds, and is constructed to deliver a full face-level fit thanks to its elongated shell and extended chin EPS. The Pinlock® 120XLT® DKS467 Ready HJ-39 shield offers 99% UV protection and scratch resistance, ensuring clear vision and durability.
