I don't think the pics do it justice and don't help the analysis. Whenever I look at a helmet, my first reaction is a visceral one. What does my gut say? Sometimes I immediately know, and these are "safe bet" helmets. No one who knows anything would dispute a "safe bet" helmet. Next I presume it fake and let the helmet tell me otherwise. My gut reaction on that helmet flipflopped as I scrolled through the pics. If it is KM, that modifies the analysis slightly because I've found their paint colors and paints looked a little different. I really want to like it, but my paranoia (well founded) gets in the way.
So, the put my money where my mouth is answer: I'd ask for more pics. If it was high priced I would want a 3 day inspect / no questions asked return privilege. If it was cheap, I'd take a chance on it based upon the pics. We need more and better pics, preferably in different light. I hope this was sufficiently to the point and not too much rambling.
