Ruroc AT4.0 Carbon Raw Carbon Helmet
The iconic Raw Carbon finish makes a celebrated return with the new AT4.0 full face motorcycle helmet, now available at Moto Central, your Official Ruroc Sizing Station. This striking AT4.0 Raw Carbon motorcycle helmet showcases the expertly hand-laid T300 raw carbon fibre weave, presented under a clear matte coat. The completely redesigned AT4.0 shell incorporates significant improvements and cutting-edge technology, resulting in our safest and most comfortable helmet to date, proudly boasting the impressive ECE 22.06 safety certification. The AT4.0 Raw Carbon motorbike helmet is among the first to achieve this standard, offering riders unparalleled protection. At Moto Central, we are committed to providing you with the highest quality and safest motorcycle helmets available. As the Official Ruroc Sizing Station, we not only stock the distinctive Raw Carbon but can also order any colour and size within the extensive AT4.0 range to meet your specific needs.
The cheek pads and headliner of the AT4.0 Raw Carbon have been meticulously redesigned to provide a more comfortable and secure fit. The cheek pads feature multiple layers of multi-density foam, which can be removed for customisation or washing, and are encased in a tailor-made moisture-wicking fabric. The headliner now incorporates RHEON™ technology, with strips of reactive polymers strategically placed to reduce both linear and rotational impact forces through their non-Newtonian fluid properties, further enhancing the safety of this exceptional carbon helmet. Experience superior climate control with the AT4.0 Raw Carbon motorbike helmet's improved ventilation system, featuring open and close front and top vents that allow you to better manage the temperature inside your helmet in both warm and cold riding conditions. At Moto Central, we understand the importance of both safety and comfort for every rider.
While the AT4.0 is Ruroc's quietest motorcycle helmet ever, you can further enhance your riding experience with the optional Shockwave™ Bluetooth insert (sold separately). This seamlessly integrates into the rear of the helmet, providing high-quality audio with rich bass for up to 8 hours of playtime via a convenient USB-C rechargeable battery. Personalise your AT4.0 Raw Carbon with our wide selection of helmet visors, easily interchangeable thanks to the quick-release thumbscrews. The helmet comes equipped with a clear visor for road use and a secondary tinted visor for track days. All our visors are also compatible with Pinlock® inserts (available separately) for effective anti-fog protection.
