I have been reading a lot of great information on this site and decided I better join. I just got done rebuilding my buddies 04 KX500 from the frame up. In return he gave me his 01 KX500. I am 41 years old and have been riding since 2001. I love to ride enduros and belong to an enduro club here in So. Cal. Looking foward to many posts here. This is the bike for my buddy I just got done doing.
