I just got a 250 exc. I am told that it is a 2000. It's hard to tell. I've been looking through the internet and I can't find much info on these bikes. I want to know if the Brembo brakes that it has are standard? Where do I get a rear brake cylinder? A crankcase chain guard? If anybody can help me out with that and more questions that I will have once I get it taken apart, I would appreciate it.
