The HJC RPHA 60 Arbre MC21 motorcycle helmet combines advanced protection, aerodynamic performance, and everyday riding versatility. This medium-size helmet features a Premium Integrated Matrix (P.I.M.™) shell made with high-performance materials infused with epoxy resin and fiber tissue. Originally developed for demanding aircraft and racing applications, the P.I.M. structure helps provide enhanced impact protection, reduced weight, durability, and consistent stability. The aerodynamic shell was wind-tunnel tested using Computational Fluid Dynamics (CFD) programs to help reduce air resistance and improve stability at high speeds.
For adaptable riding conditions, the peak visor attaches and removes without tools, while the installed dark smoke sun shield offers convenient protection from bright light. The Pinlock® Ready HJ-47 visor provides 99% UV protection and features an anti-scratch coating. HJC’s Dynamic Multi-Step Sun shield system allows quick position adjustment through a bottom-mounted operating mechanism. The Advanced Channeling Ventilation System (ACS) uses three front intakes and four exhaust vents to promote full front-to-back airflow, helping move heat and humidity away from the rider.
The RPHA Premium Fit Interior uses antibacterial fabric with moisture-wicking and quick-drying properties for improved comfort during extended rides. Removable, washable crown and cheek pads simplify maintenance, and interchangeable 3D contour cheek pads fit all helmet sizes while adding reflective visibility. A double D-ring retention system provides secure fastening. The helmet includes a Pinlock® insert, installed chin curtain, and breath deflector. It is also ready for SMART HJC 11B, 21B, and 50B Bluetooth communication systems, which are sold separately. The HJC RPHA 60 Arbre MC21 is designed for riders seeking a premium full-face helmet with versatile visor options, efficient ventilation, and dependable fit and protection.
