Arai Defiant Jolly Roger Helmet

Designed specifically for the aesthetics and needs of street fighter and naked bike rider in mind, the new Arai Defiant Jolly Roger is equally aggressive and feature rich, as one would expect from a new Arai helmet. Based on the fit and comfort of the Quantum, the Arai Defiant was built for the upright riding position with its aggressive, integrated chin spoiler, which was designed specifically to guide wind around the neck and to improve the aerodynamic properties of the helmet. The Hyper Ridge Bumper circles the bottom of the shell both adding additional strength and also lowering the helmet's center of gravity, while flaring the helmet opening slightly to increase the ease of putting on, and taking off.

The Arai Defiant utilizes Arai's latest faceshield design, the SAI Max Vision Pinlock Shield with Brow Vents and includes Pinlock insert lens. The SAI Max Vision shield has been widened by 5mm left and right and offers one of the widest eyeports available for excellent peripheral vision.

Arai Defiant Jolly Roger Helmet 5 5 2 2
ARAI! Moving on up from an Arai RX-Q DNA style to Defiant Jolly Roger style by far wasn't a bad choice. Thanks Arai!! August 29, 2014
Best full face helmet for upright riding position I have ever owned! Arai quality through and through. Comfort and fit are exceptional. Excellent airflow and wide vision. The only complaint is the big ARAI sticker on the front of the helmet. I have successfully removed this sticker from every solid color ARAI helmet I've ever owned. When I peeled the sticker off the Jolly Roger 2, I discovered that the matte coat of the helmet is applied OVER the sticker - this has left me with a large glossy oval on the front of the helmet. The solution is to just leave the big advertising sticker intact on THIS model. July 25, 2014
