Street King

The streets, they’re what shape us, what makes us, and what we ride on. Every kingdom needs a king, make the streets yours with the new AT4.0 Street King full face motorcycle helmet. The AT4.0 Street King motorcycle helmet shows off a regal-renegade combination of sleek matte black with a hand laid gold etched skull and grey steel accents that’s only fit to be worn by a king of the streets! The all-new AT4.0 motorbike helmet presents a new shell that has been refined and redesigned from the feedback from our customers and our engineers have created a perfect blend of safety and style with the AT4.0 Street King full face helmet. The AT4.0 rocks an impressive ECE 22.06 safety certification making it truly stand out on the streets with its phenomenal safety performance. The Street King motorbike helmet also offers comfort suitable for a king with the new intelligent contouring cheek pads. The new cheek pads are made from a premium tailor-made fabric that has sweat-wicking properties encasing many layers of multi-density foam which provide the new ECE 22.06 fit. 

With safety and comfort for a king, we took the 4.0 to the next level and improved its acoustic performance by 57% from previous iterations of AT to give you a quieter and more streamlined shell with the removal of the two top vents and the additional sound dampening ear inserts. For even further improved safety we partnered up with RHEON™ to bring the headliner from our RG1-DX snow helmets to the AT. The AT4.0 motorcycle helmets now has a RHEON™ headliner that uses reactive polymers which have non-Newtonian fluid properties to reduce rotational and impact forces along with the EPS. 

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 Street King 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).
