Il start by introducing myself, I live in NE ohio and have been riding quads and bikes since i was old enough too. for the last few years i have been on a quad and raced xc. ive been playing around with 2-smokers for the last 2 years but decided i want to switch back to a 4. Ive started looking for a yz450 but im not near as knowledgable with bikes as i am quads. what im wondering is what should i be looking for when i look at a bike? what are some tell-tale signs that the bike has been to hell and back? im looking in the 03-05 range or somewhere right in there. what should i expect to pay for a bike in pretty good shape in those years (built or stock)? Thanks in advance for any responses.
