The HJC RPHA 72 Carbon Lis Full Face Motorcycle Helmet combines lightweight carbon construction with refined aerodynamics, advanced airflow, and premium riding comfort. Its carbon shell is engineered for high strength and effective impact dispersion while helping keep overall weight low for reduced fatigue on longer rides. Wind tunnel-tested aerodynamics help minimize drag and improve stability at higher speeds, while the ACS Advanced Channeling Ventilation System moves air from front to back through two intake vents and two exhaust vents to help evacuate heat and humidity. The Pinlock-ready HJ-48 visor provides 99% UV protection and features an anti-scratch coating, smooth ratchet operation, improved sealing, and a push-release visor lock. A dynamic multi-step internal sun shield adds distortion-free clarity with an anti-fog coating for changing light conditions. Inside, moisture-wicking and quick-drying interior fabric, removable and washable crown and cheek pads, glasses grooves, and an emergency cheek pad release system support comfort and convenience. A titanium double D-ring chinstrap provides a secure closure, while carbon-specific details and compatibility with HJC 21B and 50B Bluetooth systems complete the premium package.
