Arai XD-4 Diamante 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 M2010 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 XD4 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 XD-4 is the helmet of choice for many hardcore ADV enthusiasts and sets an industry standard for comfort, quality and safety.
- Comfort headliner, with micro fitting 5mm peel away temple pads
- Fully removable/replaceable/washable Interior: Comfort head liner, Cheek pads, Chinstrap covers

Reviews & Questions
My major concern before purchasing was wind noise but my experience has been that the bike, windscreen, and my body height is more of a factor than the helmet. My normal riding position on the BMW puts me just inside the turbulence zone of the air going over the windscreen. If I stand up slightly (+3”) on the pegs it puts my head into the relatively smooth air coming over the screen. If I do a super-bike tuck or lean forward lowering my position I get completely behind the screen with 95% of the air blocked. My other helmet, for riding on the Ducati Streetfigther, is an Arai RX-Q. The Streetfighter has ZERO wind protection and the RX-Q is quite tolerable for noise up to freeway speeds and no ear protection. The RX-Q on the BMW is noisy from about 30 mph up. The XD-4 is almost exactly the same, with the turbulence causing a general rumbling noise in both helmets. With either helmet if I stand up on the BMW into the direct air the noise level drops. If I lean forward behind the screen they both are very quiet. So for ME, on the BMW, with this particular setup, the XD-4 behaves noise-wise very closely to the RX-Q (which I find very tolerable). BTW, this particular windscreen setup while not perfect is a good compromise, it blocks the blast of air on your chest and doesn’t intrude on forward visibility.
Some other comments after about 2k miles and a couple of long trips ...
On a March three desert tour in Calif. with temps in the 90’s I found the ventilation to be excellent, noticeably better than my RX-Q. However, on very cold mornings going over mountain passes the more open neck area of the XD-4 lets in more air than the RX-Q. I end up putting on my Klim neck gaiter sooner than with my RX-Q.
I wear prescription glasses and purchased Scott OTG goggles primarily for low speed, hot weather, off road travel. The goggles just barely fit inside the face opening of the XD-4 and require a bit of fiddling to get over the glasses but inside the face opening. Other brands/types of OTG goggles may or may not fit. Obviously the airflow with the shield up and goggles on is even better.
The XD-4 has very good peripheral vision, but obviously not with goggles on.
On the desert trip and over a series of days of high winds the helmet developed, depending on wind direction/angle to the helmet, a very loud low frequency humming/buzzing noise. It got to be really annoying. I discovered that the screws holding the visor on the helmet had become slightly loose, snugging them up tight made the problem go away.
Summary. A great helmet for what it is designed to do with amazingly few downsides when compared to its all-pavement cousin the RX-Q. A bit pricey but worth it. I would buy another. Attached "selfie" photo gives an idea of the close fit with OTG goggles on.

I'm about to head to the Himalaya's for 2 weeks, and considering getting this helmet as I'll be riding in all sorts of conditions, weather etc. My question is about goggles.
I'm considering getting the Liquid Image Torque 368 or 369 HD Goggles that will allow me to take video from my POV (without sticking my GoPro on the helmet). My question is:
"Can anyone confirm that the LI Torque Goggles fit this helmet?"
I'd hate to buy a $650 lid + $400 goggles and they don't fit...
