The Arai Defiant Helmet was designed with the naked rider in mind. Especially over the last decade the "streetfighter" look, both streamlined and mean, has become very popular among youthful and style-conscious riders. The Arai Defiant, formerly known as the Arai Rebel helmet, was designed to match the look while providing features which will cater to a protective, stable and functional helmet setup in a varying degree of riding positions.

At first glance the fit is going to be similar to the Quantum with an intermediate round shape to the aggressive shell. Also the new chin spoiler / wing on the Arai Defiant Helmet will allow for better stability in a mix of positions on a bike with no fairing. 

The new style chin vents have been added just to be boss on this much more aggro' lid from Arai.
