ST 501 is Airoh's new sports and touring full-face helmet, with roots deep in racing.

The HPC composite outer shell with multi-density EPS interior ensures light weight yet high safety. The modern and aerodynamic design is outstanding. Sufficient ventilation is ensured by well-thought-out solutions, and the extra-wide field of vision visor provides additional safety. Of course, this class of helmet comes with an anti-fog Pinlock film and is equipped with an internal sun visor, windstopper, DD chin strap, and a removable and washable lining.
