Looks very tempting.
Whether you get, Chinese or Japanese, be ready to either lower your performance expectations or take on the maintanance jobs yourself. I've never been satisfied with the service I got on my bike here, and in general I had to check what mechanics are doing and tell them were they've missed grease, where to use new washers. I had to replace a sprocket today. Sellers said no problem, it will fit.. I have a Chinese bike, and they still had no idea. I had to take off the wheel by myself, compare and eventually somehow got the job done. There are some issues I'm not sure about, so I'll ask here see if someone can help out. But I've seen all types of bikes around, mostly japanese. Can't remember ever seeing a KTM anywhere.. So they must be getting parts somewhere.
Good luck man.
