The HJC RPHA 40 is not just a helmet, but the result of years of research and development, designed for the motorcyclist who accepts no compromises. The shell sets a new standard: it is made with PIM II (Premium Integrated Matrix), a matrix of high-performance fibers (including special fabrics and Prepreg epoxy resin, typical of aeronautics and racing). This complex lamination offers maximum impact resistance while ensuring superior lightness.
Excellence continues in aerodynamics: the seamless Unibody design, rigorously wind-tunnel tested, ensures exceptional stability even at the highest speeds, reducing air resistance. The advanced antibacterial fabric interiors, soft and quilted with a leather-like finish, guarantee optimal breathability and quick-drying. The HJ-46 visor boasts an innovative fastening system with metal inserts for a sleek and clean aesthetic. Every detail, down to the new and secure Micro Bukle retention system, has been refined to offer excellence.
