Ruroc AT4.0 Carbon Liquid Carbon Helmet
The iconic Liquid Carbon design returns with a stunning upgrade in the Ruroc AT4.0 full face motorcycle helmet range. Available now at Moto Central, your Official Ruroc Sizing Station, the AT4.0 Liquid Carbon showcases an ultra-futuristic aesthetic. Crafted with meticulous precision, the raw, hand-laid T300 carbon fibre weave is exposed beneath a gleaming clear gloss coating, making this helmet a true work of art for discerning riders. As your trusted Ruroc partner, Moto Central not only stocks the impressive Liquid Carbon but also offers the entire spectrum of colours and sizes within the AT4.0 collection. If you have a specific colour or size in mind, simply inform our team, and we will gladly order it for you.
The AT4.0 Liquid Carbon motorcycle helmet isn't just about looks; it's packed with advancements in safety and comfort. The newly designed cheek pads feature a premium, sweat-wicking textile and multiple layers of multi-density foam, providing a customisable and comfortable fit. These cheek pads are also removable for washing, ensuring lasting freshness. In a commitment to rider safety, Ruroc has partnered with RHEON™, integrating strips of their innovative reactive polymer into the AT4.0 headliner. This technology helps to significantly reduce both rotational and linear impact forces. The AT4.0 Liquid Carbon motorbike helmet proudly boasts a phenomenal ECE 22.06 safety rating, a testament to its superior protective capabilities. At Moto Central, we are dedicated to providing riders with the safest and most advanced motorcycle helmets available.
Experience enhanced climate control with the AT4.0's new open and close top and front vents, allowing for optimal airflow in varying temperatures. Furthermore, the inclusion of sound-dampening inserts contributes to a more enjoyable ride. While the AT4.0 Liquid Carbon is Ruroc's quietest helmet to date, 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 USB-C rechargeable battery. Customise your AT4.0 Liquid Carbon with our extensive range of helmet visors, easily interchangeable thanks to the quick-release thumbscrews. The helmet comes with a clear visor for road use and a secondary tinted visor for track days. All visors are also compatible with Pinlock® inserts (available separately) for effective anti-fog protection.
