The HJC RPHA 90S is a great modular helmet by HJC for Adventure/Touring riders. A modular helmet is ideal for those who spend many hours in the saddle. This, because they cover your entire head like a full face helmet does and offer the convenience of a jet helmet thanks to the flip-up chin piece. If you are on the market for a helmet built for comfort, modular helmets are the way to go. If this RPHA 90S is not the helmet you are looking for, don’t worry we have a lot of other HJC modular helmets () in our collection.
