Arai XD-4 Detour Helmet

The Arai XD4 is world renowned for being the one of the best ADV touring helmets on the market and one of the few that achieves a Snell M2015 safety rating. The XD4 incorporates all of the same great qualities found in Arai's other helmets, including the comfort liner and cheek pads that feature 5mm peel-away pads that allow riders to tailor the fit. The shell of the XD-4 has also been aerodynamically tuned and, in concert with the removable floating peak visor, funnels air into the redesigned vents, improving overall ventilation and mitigating buffeting at speed. 

The Arai XD-4 is the helmet of choice for many hardcore ADV enthusiasts and sets an industry standard for comfort, quality and safety.

Features:

  • Comfort headliner, with micro fitting 5mm peel away temple pads
  • Fully removable/replaceable/washable interior liner, cheek pads and chinstrap cover
  • Dry-Cool technology keeps you dry and cool for greater comfort
  • FCS (Facial Contour Support) cheek pad design with a 5mm peel-away micro fit feature
  • Improved shell shape for better aerodynamic stability at higher street speeds
  • Exhaust ports added to the top diffuser vents
  • Chin vent with more intake ports
  • Larger sculpted side cowl vents improve ventilation
  • Snell M2015 approved

Note: Helmet ships with non-Pinlock-ready face shield. Arai XD-4 Brow Vent Pinlock-Ready Face Shield sold separately.

Great helmet!
Don't have a ton of time on it, can't speak for the durability. Hopefully I won't have to attest to it. Does flow a ton of air. I was worried about the peak catching the wind and pulling the helmet but it's not as bad as some make it out to be, even above highway speeds.

One thing to note the helmet does seem slight larger than my older Vector 2. Going to have to pick up a set of thicker cheek pads.

Awesome helmet
Great helmet but a little pricey for what you get. Don't get me wrong I love the helmet but I think you are paying for that Arai stickers on it I wore a medium in Bell and fit right in to this helmet in a medium.

Great Helmet - But Something Bugs Me!
I've been enjoying this helmet for about a month, and during that time the majority of my riding has been ADV / Dual-Sport. I bought this helmet because Arai have long been the masters of protection and comfort in the ADV world, and I was looking to upgrade from my heavy modular lid.

For the price, I would say that this helmet is awesome but not remarkable. Some of that $600 is definitely because it says 'Arai' on the side, but in truth it is the most comfortable helmet I've ever worn. Light (considering features like vent adjustment and a built-in visor), plenty of airflow, a wide viewport, and great looks.

I've also managed to hook up my Sena 10c to this; they are supposedly incompatible but that's just because of the length (or lack thereof) of the wiring on the 10c. If you're willing to pull out a cutting tool and do some splicing (sssh! Don't tell Sena!) it fits a charm!

I've got a couple of minor things I'd like to see, like a less stiff visor lock mechanism and more finish around the jawline vents, but whatever.

My only major gripe is something I never would have thought of: there is SO much airflow from the shield area to the back of the head that when the shield is open and I'm riding between 15-45mph and I encounter a flying bug, they get SUCKED IN past my ears and shot towards the back of the helmet! I mean, that's an impressive amount of airflow!

The bugs ride this tiny river of air right to the back of the helmet like a log flume to hell. Unfortunately, they cannot be vented out that way as the channels narrow to the exhaust vents. This leaves me with live crawlies on my scalp or the back of my neck if I fly through a cloud of gnats or what have you. This leads me to keep my shield down more than I have on other helmets, and means that I sometimes have to keep calm and pull over while something is squirming on my head.

The bug issue is probably common with low-weight, high-flow open-faced helmets, but I've never had it happen to me before, and it is my least favorite thing about the XD-4.

That weird issue aside, this is a fantastic lid and I love owning it.
