No, it will not bolt in. Also, that is way over priced for a used engine. It is worth at best, half that.

Why would it not bolt directly in? '06-'09 are 95% identical bikes. That engine is a bolt-in.

BTW, Please alert me if ever you should see an '07+WR450 engine at $900, too.

With 10-20 hrs, if legit, is a decent price, and it will bolt right in.
