The classic Liquid Carbon as seen in the previous generation comes with all its shiny glory to the new AT4.0 full face motorcycle helmets line up. An ultra-futuristic design that has been crafted with expert precision and dedication, exposes the raw hand laid T300 carbon fibre weave of the helmet with a clear gloss coating. The newly redesigned shell of the AT4.0 shows off the exquisite carbon fibre weave as a true work of art for all motorcycle riders. The new shell also is packed with several improvements from our last generation of Liquid Carbons. The newly redesigned cheek pads have a premium tailor-made sweat-wicking textile, encasing multiple layers of multi-density foam which can be removed for washing or further rider customisation. We have teamed up with RHEON? to further improve the safety of our motorcycle helmets. The AT4.0 headliner now has strips of reactive polymer developed by RHEON? to help reduce rotation and linear impact forces on a rider's head. Now is your chance to get your hands on a truly refined and improved version of the stunning AT4.0 Liquid Carbon motorbike helmet with all the new features and it is now rocking a phenomenal ECE 22.06 safety rating which has only been achieved by a few other helmets on the market. The AT4.0 now includes open and close top and front vents for enhanced climate control in both cold and hot temperatures and with the addition of sound dampening inserts to further make the ride more enjoyable.
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 Liquid Carbon 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).
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.
