Ruroc AT4.0 Carbon Surtr Helmet
From the fiery depths comes the Ruroc AT4.0 Surtr full face motorcycle helmet, now available at Moto Central, your Official Ruroc Sizing Station. This visually striking helmet embodies the fire giant Surtr, featuring a flaming grin and lava patchwork in vibrant reds and oranges, contrasted with deep blues and tinted elements. Ride with the fierce style of the AT4.0 Surtr motorcycle helmet and command attention with its impressive and demonic decal. At Moto Central, we are proud to offer this unique Surtr design and, as your dedicated Ruroc partner, we can order any colour and size from the extensive AT4.0 range to meet your exact preferences. Simply let us know your desired specifications, and we'll arrange it for you.
Safety is paramount, and the AT4.0 Surtr helmet boasts an impressive ECE 22.06 safety certification, ensuring top-tier protection for every ride. Comfort is equally important, with new cheek pads crafted from premium sweat-wicking fabric and multiple layers of multi-density foam, providing enhanced intelligent contouring for a superior fit. The headliner now features RHEON™ technology, which increases energy dissipation using reactive polymers to reduce both rotational and linear impact forces. The AT4.0 motorbike helmet also features a more streamlined shell, significantly reducing wind noise. Coupled with the included sound-dampening inserts, you'll experience quieter acoustics and less strain on your neck, allowing for longer, more comfortable rides. The open and close vents on the front and top of the helmet offer a total of four adjustable positions, providing greater climate control in both hot and cold environments. At Moto Central, we prioritise both your safety and your comfort on every journey.
While the AT4.0 is Ruroc's quietest motorcycle helmet ever, you can further enhance its functionality with the optional Shockwave™ Bluetooth insert (sold separately). This seamlessly integrates into the rear of the helmet, delivering high-quality audio with rich bass for up to 8 hours of playtime via a convenient USB-C rechargeable battery. Customise your AT4.0 Surtr with our wide range of helmet visors, easily interchangeable thanks to the quick-release thumbscrews. The helmet comes equipped with a clear visor for road use and includes a secondary tinted visor for track days. All our visors are also compatible with Pinlock® inserts (available separately) for effective anti-fog protection. Visit Moto Central today, your Official Ruroc Sizing Station, to explore the formidable Ruroc AT4.0 Surtr and discover the full spectrum of Ruroc helmets and accessories available.
