I am new to the forum postings but have lerked around for a while now. Done some research for what I want for my new dirt bike. I currently own a 83 xt 550. I have mastered the old thumper but want a lighter more nimble trail bike. I use it mostly to ride in the mountains of montana and cruise around the north and south 40. I would like a 04,05 wr 450 any tips on what I should be looking for in a used bike of that era? I would like to find a used hold over 04 or 05 but would be willing for used if I can find a clean one and know what to look for. Thanks for the info. jon edit... I guess I shouldn't say that I have mastered the old thumper but I have rode it to its limits. what can i expect from a new 450?
