The streamlined shell features fully adjustable front and top vents for precise temperature control and improved acoustics to reduce turbulence and wind noise.

The AT4.0 is a fully Bluetooth compatible motorcycle helmet when used with the Shockwave Bluetooth sound system included with this helmet. Featuring sound engineering by Harmon Kardon, the Shockwave integrates seamlessly into the AT4.0.

We offer seven additional coloured visors that can be changed in a matter of seconds with our tool-less thumbscrew mechanism. Your AT4.0 comes as standard with a clear visor installed and a tinted visor included in the box.
