AT4.0 Liquid Carbon RR

Pure carbon. Zero distractions. Maximum performance.

AT4.0 CARBON Liquid Carbon strips away graphics and colour to showcase the material that defines the helmet. Finished in a deep high-gloss clear coat, every layer of carbon fibre remains fully visible, highlighting the precision weave and craftsmanship beneath. Clean, understated, and undeniably premium, Liquid Carbon is built for riders who appreciate performance engineering in its purest form.

Constructed from lightweight carbon fibre, AT4.0 Carbon delivers exceptional strength, stability, and aerodynamic efficiency without unnecessary weight. Designed for riders who demand confidence at speed, the helmet remains composed in changing conditions while reducing fatigue on long-distance journeys and high-performance rides alike.

Inside, the Sport liner combines a soft-touch feel with a secure, performance-focused fit that remains comfortable hour after hour. Every contact point has been refined to provide a premium riding experience, whether you're commuting daily, exploring new roads, or pushing harder when the opportunity arises.

Advanced RHEON impact protection technology adds an additional layer of safety, while the Fidlock magnetic chinstrap allows quick and secure fastening every time you ride. Certified to ECE 22.06 and DOT standards, AT4.0 CARBON Liquid Carbon also features a wide 215° field of view and a Pinlock-ready visor system for enhanced visibility in all conditions.

Designed around versatility, the platform is fully compatible with Shockwave Bluetooth Audio (sold separately), allowing seamless integration of navigation, music, calls, and rider communication without compromising the helmet's clean, minimalist aesthetic.
