HJC RPHA 10 Helmet
Designed for superior fit and comfort using advanced CAD technology, the HJC RPHA10 helmet is constructed from Advanced Premium Integrated Matrix, a composite of carbon fiber, fiberglass epoxy, aramid epoxy and organic fibers resulting in a remarkably strong & extremely lightweight helmet. The HJC RPHA-10 uses the same guts of the RPS 10, which offers a racer comfort and protection on the street and track. The HJC RPHA, as well as the replacement parts on this page, continue what the RPS 10 started with aerodynamics, style and features that cater to the competitive racer and track day elite.
