Fenrir the wolf with unparalleled strength and boundless evil, not even the spell-cast chains, conjured by the Gods, could prevent the chaos Fenrir will cause in the doomsday that is Ragnarok. The AT4.0 full face motorcycle helmet introduces an intricate handcrafted gold leaf design, featuring Fenrir the wolf and its snarling teeth, shrouded in ornate urnes style pattern-work. This is the ultimate motorcycle helmet for the leader of the pack or the lone rangers. The AT4.0 Fenrir is one of the first motorcycle helmets to ship with the impressive ECE 22.06 safety rating, Ruroc's AT4.0 helmets surpassed all tests by at least 20%. Comfort is key for long rides and the AT4.0 Fenrir motorbike helmet has brand new cheek pads which are constructed from a premium sweat-wicking fabric and contain multiple layers of multi-density foam allowing intelligent contouring around your face. We have partnered up with RHEON? to give you a reactive polymer headliner with extra foam padding for comfort. The reactive polymers have non-Newtonian fluid properties which help reduce linear impact and rotational forces and keep your head even safer.?
With the new streamlined shell, long rides will be less strenuous on your neck muscles as there is less air resistance on the helmet, this also helped with our mission to make the helmet quieter. The sound dampening ear inserts along with the streamlined shell provide a quieter acoustic experience which can help to lessen rider fatigue over longer distances. Climate control has never been better in an AT helmet with the front and top vents being fully adjustable with a total of 4 positions so you can adjust the temperature of your head in both hot and cold climates.?
The AT4.0 is Ruroc's quietest motorcycle helmet ever but why not improve the functionality and entertainment and upgrade it to a Bluetooth motorcycle helmet with our Shockwave? Bluetooth insert (sold separately). The AT Shockwave? is easily installed with a seamless fit into the rear of your helmet. The AT Shockwave? now has a 60% smaller mic and low-profile speakers that deliver high-quality audio with rich bass for 8 hours of playtime with a USB-C rechargeable battery.
The AT4.0 Fenrir can be transformed and customised with our wide range of helmet visors. We offer 7 additional coloured visors that are easily changeable with our quick release thumbscrews. The helmet comes with a pre-installed clear visor for road use and a secondary tinted visor for track use only. All our visors are compatible with Pinlock? inserts that can easily be installed for anti-fog protection (available separately).
