What's this?

Arai Defiant Pro-Cruise Mimetic 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.

  • Shell shape is easier to put on and take off than previous helmets

Arai Defiant Pro-Cruise Mimetic Helmet 4.6 5 150 150
Good but not great Helmet is noisy and doesn't cover the entire chin. Comfort is good and protection I can't say as I haven't had to use that. But from what i read its great protection. It also leaves a slight mark on my right chin not sure if the padding is un-even. This is a good helmet but for the price I think one can do better. I will certainly look for something quieter, and lighter in future. The quality of materials is good and construction is solid. June 28, 2016
Awesome Helmet! This is the first "Premium" helmet I've owned. The fit is perfect for my head shape, it's comfortable, durable, and truly a premium product. The vents and face shield mechanisms are rugged and well built, very unlikely to break under heavy / frequent use. I really like ARAI's system for removing the face shield as well, it can take a little practice, but RevZilla has a video for that. :) I highly recommend buying a tinted face shield, really gives the helmet an aggressive look. Only thing I don't like is the noise, it's louder than other helmets I've owned. Pros: Fit, Comfort, Durability, Quality, Style Cons: Loud, very loud. I'll only buy ARAI from now on, and I'd recommend this product to anyone. June 14, 2016
Love this helmet Having owned 4 other Arais over the years, this is another winner. Extraordinary fit for my intermediate oval head. 1 year and almost 9K miles, this is my new favorite helmet. Flows air like nobody's business. Great chin vent in particular. Visor secures 100% waterproof, no leaks in several heavy rain rides. Pinlock being included was a nice perk and helps keep fogging to a minimum. Awesome 5 star helmet. Wish Arai offered a photochromatic visor. May 26, 2016
Great Helmet! Great service! This Helmet is Great! But the best part of this buying experience has been Revzilla. The helmet is an Arai and is a huge up grade for me both in fit and function over the Bell I had. The venting is incredible moving so much more air than I ever expected. The pro shade system works great too but I've already ordered a longer visor. The stock one seems too short. As for Revzilla, I ordered the wrong size helmet (my head is on the line between MD/LG) and had to return the MD. The speed and ease in which they handled my return was amazing. I reordered the right size and was off and riding in a few days! May 16, 2016
1 week use of the Arai Asteroid (Green version) Summer time desperation buy due to emergency need for a new helmet. As far as looks, mostly positive feedback from other riders and the general public. No negatives expressed so far. The green is more of a neon, so it doesn't really match Kawasaki green 100% up close anyway. Positives: 1. Reduced fog compared to non-pinlock helmets (not 100% but 95% I'd estimate and any fog buildup eventually disappears) 2. Good peripheral view (better than it's competitors in the same price range - sale price) 3. Very comfortable fit - for a medium, intermediate oval which I wear in other similarly priced brands. Negatives: 1. LOUD - it's definitely louder than other brands, including my older RF-1000 (Jay Leno probably loves this kind of road noise but I prefer hearing music) 2. The visor lock is a pain, trying to unlatch it with summer weight gloves is a near impossible task 3. I ride vintage bikes & sport bikes. This helmet is not great in the full tuck position, so Revzilla's Youtube review is spot on - full upright to 3/4 tuck is what it can do. I've bought 3 Revzilla reviewed products this year and Revzilla has been 95% spot on in their reviews so far. May 10, 2016
It's hard buying helmets online. I got this helmet because of aria helmets good reputation. Unfortunately the helmet does not fit me as well as I expected. I purchase this helmet under the sizing guidelines and while standing still in my house it fits me perfectly, but when I'm out on my bike I get a severe tension headache. By the time I was aware of this issue it was too late to return the helmet. Now I have a $600 helmet that I've worn three times, sitting in the box and I'm not allowed to refund it due to RevZilla's return policy. I was advised to sell locally by the geek I spoke with.

Great Helmet- but Pro Cruise not so much I have now put over 1000 miles on this helmet and must say the Arai Defiant (I'll talk about the Pro Cruise system below) is amazingly comfortable and extremely well built. It has great airflow which helps with 80+ degree weather in the summer, but doesn't suffer from excessive fogging or air leakage when you close the vents during sub-40 degree riding in the winter. I have two minor gripes with the helmet itself- 1) the integrated chin curtain is a bit small and doesn't block as much air as I'd like. 2) the visor locking mechanism is extremely difficult to use, especially with gloves on. As for the Pro Cruise system- I don't think it is a worthwhile accessory. When it's down it doesn't quite come down far enough- especially on the sides- to truly block all the light you'd like it to. And when it's up, boy is it annoying! It doesn't upset the helmet terribly, but it does act as a bit of a sail on top of the helmet, and it DEFINITELY makes the helmet LOUDER up or down. I could see it working fine for someone who's entire commute take place at <30 mph. I've ended up replacing the Pro Cruise system and the included clear face shield with a mirrored one from Arai which is amazing- really blocks the light and actually helps the helmet stay cooler.
