HJC RPHA 72 Carbon Fynex Adult Street Helmets
The RPHA 72 Carbon Fynex is a premium full-face helmet from HJC, engineered for riders who demand lightweight performance and confidence at speed. Its advanced carbon shell uses high-performance materials inspired by aerospace applications, delivering excellent impact dispersion while keeping weight to a minimum to reduce fatigue on longer rides.
Wind tunnel tested aerodynamics enhance stability at higher speeds, while the Advanced Channeling Ventilation System channels air from front to back to flush heat and humidity out of the helmet. A Pinlock-ready HJ-48 visor with smooth ratchet operation and a secure visor lock provides clear vision and dependable sealing, while the distortion-free internal sun visor allows quick light adjustment on the move. Inside, the antibacterial, moisture-wicking liner, eyewear-friendly fit, and emergency release cheek pads complete a helmet built for performance, comfort, and everyday riding.
