Nolan N104 Action Helmet Nolan N104 Helmets represent an evolutionary step for Nolan as they replace the much touted N103 Helmet. When compared the older N103, the Nolan N104 Helmet offers a helmet which is much lighter (7oz), features a lower profile through the use of multiple shell sizes, better aerodynamics, as well as a much larger viewport for increased visibility. The (patented) chin guard rotation movement with elliptical trajectory makes it possible to keep the total size of the helmet's front section to a minimum, when the chin guard is open. The sail effect is consequently highly reduced and riding comfort is still guaranteed, even when the chin guard is lifted. The new ultrawide eyeport is the largest of any Nolan helmet, both vertically and laterally for maximum field of view. The AIRBOOSTER ventilation system is equipped with an air intake in the chin bar, another intake in the brow and two rear extractors at the rear. The inner comfort lining includes removable cheekpads, inner liner, neckroll and chin curtain and is easily removable and washable as well as antifungal and antibacterial. New, redesigned comfort liner also accommodates eyeglasses much more easily than before. All Nolan N104 helmets are also N-COM B4 ready ( N-COM B4 is designed expressly for the N104 and is sold separately).
