St 501 is a new full-face helmet for touring and sports with a strong racing soul.

Both outer shells in high-performance composite HPC fibre – available in two different sizes – and inner EPS shells – available with 4 different densities – ensure a high level of safety while keeping weight down.

Modern lines and an aerodynamic design make this product perfect for escapes from the city in the warmer months and all the year round, through its ventilation system that keeps the inside of the helmet cool under any circumstances. The helmet – equipped with a windstopper and a wide inner sun visor paired with a Pinlock® lens – will give riders all the safety they need. Light weight, protection and out-of-the-ordinary design combine perfectly in this new full-face Airoh model.
