The reinvented RPHA 90S Carbon is the most compact modular helmet, resembling a full-face helmet through weight and appearance, yet functioning as a modular helmet. The Premium Carbon Fiber Outer shell provides enhanced shock-resistant performance and a comfortable and very lightweight helmet using reinforcement materials that include carbon and carbon-glass hybrid fabric. The RPHA 90S Carbon has a 3D-engineered low-noise interior that is focused to reduce noise significantly for riders. Another convenient feature is the EPS design that accommodates riders who use eyewear and also has recessed areas for custom speaker placement. SMART HJC Bluetooth is available.
