Leslie Houston,  TX Fine fit and finish This has been a great helmet; will most likely purchase another Arai. However, the side plates have broken twice with normal usage and trying to buy replacements is difficult - no one seems to know how to look up the part. In addition, I have bumped the top vents - another difficult part to purchase. So, other than the lack of support on parts, it's been a great helmet.

JoeSchmo Appleville,  CA Quantum II is awesome This helmet is great. Tried many helmets and this works the best for me. The helmet is over $500 but your head is priceless. Functions awesome and looks great doing it.
