The AT4.0 CARBON - Liquid Black is a lightweight weapon, combining the performance of our signature carbon fiber shell with Ruroc's brand new cutting-edge Liquid gloss coat technology. Designed to offer an unmatched finish like nothing you've seen before on a Ruroc helmet.
The AT4.0 full-face motorcycle helmet ticks all the boxes for safety, comfort and style. Composed of multi-layered, multi-density foam, our tailor-made cheek pads intelligently contour around your face for a custom fit.
The AT4.0 headliner has been enhanced with RHEON? technology that helps reduce impact and rotational forces using reactive polymers for increased energy dissipation. Fully ECE 22.06 certified, the AT4.0 is our safest helmet yet.
The streamlined carbon fibre shell features fully adjustable front and top vents for precise temperature control and improved acoustics to reduce turbulence and wind noise.
The AT4.0 is a fully Bluetooth compatible motorcycle helmet when used with the Shockwave Bluetooth audio insert (sold separately). Featuring sound engineering by Harmon Kardon, the Shockwave integrates seamlessly into the AT4.0.
Your AT4.0 can be customised with our range of helmet visors. We offer seven additional coloured visors that can be changed in a matter of seconds with our tool-less thumbscrew mechanism. Your AT4.0 comes as standard with a clear visor installed and a tinted visor included in the box.
The new standard for safety

ECE 22.06
ATLAS 4.0 is one of the first motorcycle helmets on the road to meet ECE 22.06. Not only that, we exceed all testing standards by a minimum of 20%, to give you the ultimate protection.
Helmet Features
Ultimate Comfort
The fully re-engineered internals, including head-liner and cheek pads, take fit, comfort, acoustic control and support to a whole new level.
Quieter than ever
The ATLAS 4.0 internal lining is equipped with new sound-dampening inserts around the ear structure. This improves acoustic performance by 57%*, making it the quietest ATLAS ever produced.
Climate Control
Take full control of your helmet environment with open/close vents throughout - including the addition of a new top vent switch.
Maximum Vision
Featuring 215° horizontal and 100° vertical field of vision, the ATLAS 4.0 edge-to edge visor maximises peripheral vision. Anti-scratch dipped, Pinlock 70 compatible, and made from Optical Grade Ballistic Polycarbonate, this is vision reinforced.
RHEON? Protection
The world’s first road-ready motorcycle helmet to feature RHEON? technology. Next-level protection seamlessly integrated into the ATLAS 4.0 head-liner.
Bluetooth Audio
Convert your ATLAS 4.0 into a full Bluetooth motorcycle helmet with our Shockwave audio system. Plug into your favourite tunes, and take calls. It fits seamlessly into the back of your helmet, without compromising on the style, safety and aerodynamics of your setup.
