I am looking into purchasing a KTM 200. What are the differences between the exc & mxc models? Are there any changes in the models between the 1999, 2000, 2001, & 2002 models? I might be able to pick up a leftover 00' or 01' at a good price. Also, does anyone know what kind of warranty comes on a new bike? I checked their website and couldn't find any info. Thanks in advance for any help. Tom:confused:
