They may be bullet proof in a sense, what I mean is they will always run but there will always be some little problem to keep you wondering. Almost everyone I have ever seen is smoking or needs a top end or has already had one. They are nice little bikes and they handle well. And if you treat them good and don't gut them they will usually last a while. Good luck on your new quad
