The AT4.0 Harley Quinn full-face motorcycle helmet has the ECE 22.06 rating, the latest and most up-to-date safety rating in Europe. The helmet also comes with the newest DOT certification. The AT4.0 features redesigned cheek pads that are made from a premium sweat-wicking fabric that will keep your face moisture-free. Inside the outer fabric, you will find multiple layers of removable multi-density foam. In the event of washing your helmet liners, you can remove the foam to increase the life span and cushiness of your helmet padding.?

The headliner now features integrated? RHEON? technology in between the foam and the EPS. The AT4.0 is one of the first helmets to use a reactive polymer to help dissipate energy away from your head in the event of a collision. RHEON is a non-newtonian fluid and it is soft and malleable when moved slowly but when you hit it, it solidifies and absorbs energy from the impact. This will reduce linear and rotational impact forces from reaching your head and with most helmets only protecting your head from linear impacts we now offer rotation impacts protection.?

The new shell of the AT4.0 offers the rider a smoother and quieter riding experience. With a 57% acoustic performance improvement over previous AT models the 4.0 is truly our quietest helmet yet. With a more streamlined shell, this helped with the wind noise and now you will experience less air resistance when riding, allowing your neck to undergo less force from the wind. To help us accomplish the improvements to the shell we removed the two rear top vents. To make sure you would still get enough airflow inside the helmet the AT4.0 now features a 4 stage climate control system so you can ride in cool and hot environments without discomfort. The ventilation system is composed of the front chin and front top vent with air exiting at the rear of the helmet.

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 Harley Quinn 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).
