Looking at a locally listed 2006 yz450f. Im pretty sure the 50th anniversary is just a plastics package and so doesnt add any value to me. The owner says the bike has about 65-70 hour on it. It has a new weisco piston, and new iron man sprocket and chain. Other than that the bike is all stock. Tires are dunlops that are about 60 percent. The owner rode at a locally track so it does have some track time on it. It appears to be in very good conditionfrom the outside. Looks well maintained. He said he would take 2500.. Does this sound like a deal or something i should pass up?
