Introducing AT4.0 The Joker motorcycle helmet, ready to run the streets with meticulously detailed graphics that really allow you to show off that grin. The Joker full face helmet has all the brand-new features and safety certifications of our AT4.0 helmets, with a bit of chaos thrown in to set the tone while you're on the streets.
We listened extensively to our customer feedback when developing the AT4.0, including re-designing our cheek pads and headliner for a more secure fit and greater comfort. Our new tailor-made cheek pads and headliner feature soft, sweat-wicking premium fabric and multilayer multi-density foam sheets. The headliner enhances your protection using the latest RHEON's tech. AT4.0?helmet is now our quietest motorbike helmet with the removal of the top vents and additional noise dampening ear inserts which can be installed to greatly improve the user's experience.?
We didn't stop there though. Safety is a priority when it comes to our carbon fibre helmets and the AT4.0 has achieved the latest safety standards in Europe with the new ECE 22.06 certification. This will be one of the first helmets to hit the streets with this impressive safety rating. Our helmet surpassed all tests requirements by at least 20%.?
The awesome decal paired with our latest tech makes for an exhilarating and comfortable riding experience.
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 The Joker 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).
