The thing that scares me away (the only thing) is the stories I hear from lots of KTM owners. I mean lots of KTM owners, dozens of whom I know personally, and even more on here or other boards. Lots of little problems, fuel pumps, stalling, electrical issues, the list goes on and on.
I have NEVER, not ONCE, EVER, even ONE SINGLE TIME heard of a SINGLE issue with the WR250R. Myabe I didn't capitalize enough of those words... :)
