Airoh's new ST 501 is a full-face helmet for touring and sports use "with a strong racing soul".
Both sizes of outer shell are in high-performance composite (HPC) fibre and there are four different densities of inner EPS shell to "ensure a high level of safety while keeping the weight down". The helmet's ventilation system consists of top, chin guard and rear vents for all-condition airflow optimisation; features include a wind stopper and a wide inner sun visor paired with a Pinlock lens, "giving riders all the safety options they need".
Additional features include a DD-ring retention system, a hypoallergenic, removable and washable inner liner, a tool-less quick release, scratch and a UV resistant racing visor. The helmet weighs from 1,400 g (+/-50 g).
