The second generation of sports touring helmets to emerge from the stable of HJC and uses much of the technology and design from HJC's top-of-the-range helmets - the RPHA 71 offers HJC's Plus Integrated Matrix (PIM) shell construction of carbon fibre, aramid and carbon-glass hybrid fibre producing a solid superlight helmet. The shape of the shell itself was designed in HJC's wind tunnel to maximise its aerodynamic potential, and rear and side spoilers ensure stability at any speed. The RPHA 71 features air channels incorporated into the EPS liner; the vents have a simple slider mechanism allowing precise airflow control, and the top vent has been designed to work in both tucked and upright riding positions. For even more comfort, the helmet's anti-bacterial lining wicks moisture away and is removeable and washable. It comes with a clear Pinlock-ready HJ-40 visor with 99% UV protection that is anti-scratch coated and push and release visor lock, which is easy to open but secure. The visor also features a quick, simple and secure ratchet system. It also comes with the Pinlock 120 DKS468 insert. In addition, it has a detachable anti-fog insert, a height-adjustable 3-step internal sun visor, a 'glasses groove' for spectacle wearers, and the chin strap has a double D-ring retention.
