The HJC RPHA 1 was designed with feedback from MotoGP riders. HJC's engineers created the RPHA 1 with their input and premium safety certification. It is constructed from Premium Integrated Matrix (PIM Plus) with optimum reinforcement materials, including carbon and carbon-glass hybrid fabric for enhanced shock-resistance and a lightweight fit. The shape is ultra-aerodynamic with ACS Advanced Channeling Ventilation System with five intakes and four exhausts. Full front-to-back airflow flushes heat and humidity up and out, and this improved ventilation system reduces visor fogging and increases airflow. An enhanced Visor dual lock system is suitable for high-speed racing conditions and roads, and it comes with a clear Pinlock insert. The new HJC EASY Attachment System allows secure and straightforward tool-less Visor replacement with Silver Cool liner that provides enhanced moisture-wicking and Quick-dry with cool comfort and cooling effect for superior stability. A removable and washable crown and cheek pads that are interchangeable throughout all sizes for the perfect fit. Emergency Kit (Cheek Pads) allow for safe and quick rescue in an emergency, and it also offers recesses for speakers for communication systems. A glasses and sun friendly EPS design allows comfort whilst wearing glasses.
