The HJC RPHA 60 Arbre MC4 Helmet in Large combines premium protection, aerodynamic performance, and versatile touring functionality for motorcycle riders. HJC’s Premium Integrated Matrix (P.I.M.) construction uses high-performance materials infused with epoxy resin and fiber tissue, a structure developed with technologies used in aircraft and racing applications. This shell design helps provide strong impact protection, reduced weight, durability, and consistent stability. Wind-tunnel testing and Computational Fluid Dynamics (CFD) analysis support the helmet’s aerodynamic shape, helping reduce drag and improve stability at higher speeds.
The helmet includes a Dark Smoke sun shield and a tool-free peak visor that can be installed or removed for adaptable riding conditions. The Pinlock Ready HJ-47 visor provides 99% UV protection and features an anti-scratch coating. HJC’s Dynamic Multi-Step Sun shield allows quick adjustment using the bottom-positioned operating system. The Advanced Channeling Ventilation System (ACS) uses three front intakes and four rear exhausts to move air through the shell, helping remove heat and humidity during rides.
The RPHA Premium Fit interior uses antibacterial fabric designed to improve moisture wicking and drying performance. Removable, washable crown and cheek pads support convenient maintenance, while interchangeable 3D contour cheek pads fit across all helmet sizes and include reflective elements for added visibility. A double D-ring retention system provides secure fastening. The helmet comes with a Pinlock insert, installed chin curtain, and breath deflector. It is also prepared for SMART HJC 11B, 21B, and 50B Bluetooth communication systems, which are sold separately. This Large HJC RPHA 60 Arbre MC4 helmet is identified by manufacturer and vendor part number FA49NUS6204V.
