A buddy of mine from Scotland, who I work with, brought the May Issue of Trailbike & Enduro Magazine/Dirt Junkies. They do a review of the following 8 helmets:
AIROH S4, 110-115 GBP
ARAI TOURX2 (same as the XD3), 299-349 GBP
BMW ENDURO, 250-280 GBP
HJC CLX-2, 99.99-119.99 GBP
MARUSHIN X-MOTO, 99.99 GBP
SHOEI HORNET DS, 290 GBP
VEMAR VRX7 149.99-159.99 GBP
WULFSPORT PRIMACROSS, 64.95 GBP
I also am showing the price the mag says they run. Now keep in mind this is British Pound. Current exchange rate is 1 GBP = 1.96156 USD. So do the math. They are paying way more for the Arai or Shoei than we do. Hell I haven't even had time to check the net on these.
