The Arai Concept-X motorcycle helmet is a helmet model designed in the retro style of the 1980s, so it goes best with stripped down, cafe racer and new models of retro motorcycles and scooters. In order to preserve the classic look of the helmet, Arai developed a special ventilation system with air channels inside the helmet shell. The inner linings are flexible and fully replaceable, and the lining fabric is washable.
