My local dealer has a 2001 XR250 with less than 50 miles on it. He said that the ring seized to the piston and after it was fixed (by this dealer) the guy just traded it for a CR. I found this to be a little odd of an XR motor. The dealer said that it has been a problem with 2001 models. Still, I've never heard of such a thing. I thought the bike has pretty much gone unchanged since 1996. Why would they all of the sudden have these problems? I called another dealer and he's never heard of the problem either...of course this guy wants to sell me a new (2000) TTR250. So, thought I'd ask around here to see if anyone else has experienced this problem.
