Arai Defiant Pro-Cruise Bold Helmet

Designed specifically for the aesthetics and needs of street fighter and naked bike riders but with the added functionality of a built-in sun shade, the Arai Defiant Pro-Cruise Helmet is aggressive and feature rich as one would expect from any Arai helmet. The Defiant Pro-Cruise Helmet expands the functionality of the first generation Arai Defiant Helmets by adding the Arai Pro Shade system, which operates as both a peak and as a sun shade. The Pro Shade System is a small peak that is locked in position. Unlocking is easy; just pull the Pro Shade System forward, then it can be flipped down with a flick of the hand to act as an effective sun-visor. 

Based on the fit and comfort of the Quantum, the Arai Defiant Pro-Cruise 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 Pro-Cruise Helmet 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 Pro-Cruise Bold Helmet 4.7 5 131 131
I love it. After wearing another Arai helmet I bought, I came back for this one too. Never did understand how this brand could be so much more expensive that the competitor but it's worth the extra cost. Excellent design and attention to detail. February 8, 2016
Arai Defiant Character Helmet-Red Medium I really did not have a shop out here (CT) that is well versed or has the stock to find out. I have had Quantum, and Quantum II(2), and looking at Defiant now. I have a head size between the two helmet sizes, SM 21.7-22” 55 – 56cm MD 22.4-22.8” 57 – 58cm So I have tried previous helmets from Aria in Small and the helmet strap is cutting into my neck and wind pipe. So I have always gone to the Medium size. The Defiant helmet has more birth when putting on the helmet, and is extremely comfortable. The liner is very stable but soft feeling. I purchased the helmet during the winter and have only had ten minute ride since receiving it. In communicating with Arai customer support during the purchase it was suggested to move to a thicker check pads, after the helmet breaks in. I will move to a 30 or 35 MM size check pads to provide a great fit as it is wearing in. I will add more once I get more road time. January 26, 2016
good quality, very happy Very happy with Revzilla and my helmet as they have produced what they advertised. Will definietely shop with them again January 19, 2016
Great helmet Good fit great airflow comfortable design is really cool I love it January 19, 2016
Confidence inspiring helmet! I've always bought affordable low cost value helmets and felt that they were good enough. Well recently my helmet fell apart and I thought I'd go ahead, splurge and invest in a top of the line helmet. After much research, I decided to go with the Arai Defiant Pro Cruise. All I can say is, WOW! This helmet is like a work of art, but still built like a tank! Every aspect of a helmet that should be considered has been considered. Its comfortable, its properly ventilated (maybe a bit too much at times). The only complaint I have are the brow vents. They tend to vibrate open at times and gets too breezy in the helmet. If you are considering this helmet and can afford it, by all means get it! You will be beyond satisfied. December 28, 2015
Well built but noisey I loved the design and the construction seems solid but in use the blunt face creates a high level of noise. Even ear plugs could not reduce the sound to a level that made the helmet a favorite. Today it sits on the shelf while a lesser helmet serves the purpose. December 14, 2015
Awesome Lid I've always been a fan of Arai and this lid has fueled my love. Pinlock is great, I couldn't fog the shield if I tried. Great airflow and fairly low noise. The only gripe I have is that I wish the Pro Shade didn't tapper so much on the sides bc the sun hits eyes on the evening comumute. I was surprised, however, that the shade when flipped up makes no noise and doesn't catch wind when head checking. Overall very happy and would buy again! December 8, 2015
Amazing helmet! Okay I ride a 2015 Ducati Monster 821. I bought a shoei rf1200 and it was great, comfortable vented okay and didn't move my head alot in the wind on the freeway. It was pretty stable. But I wanted something that vented better. So I got this aria defiant. And all I have to say is WOW! With my rf1200 I had to be on the freeway for it to vent adequately as well as tilt my head down so the air could go in the vents better and at speed it would buffer in the wind a little, sometimes more. But this defiant is amazingly stable at speed. It truly is designed for naked bikes in a more upright position. And it vents SOOOO much. Better too! I thought ii tt was going to be loud from reviews I read, but it was only slightly louder not bad by any means. Absolutely love this helmet and highly recommend it if you have a bike without fairings and are in a 3/4 or more upright position riding. But I will say I don't care for the shield mechanism at all. And the shield is thinner that the shoei too. December 4, 2015
