You might want to investigate that... in Oregon, the only addition to the usual title transfer fees is a $20 or $30 lost title fee, and the cost of mailing a registered letter to the previous registered owner's last known address. The registered letter is supposed to contain a filled out lost title form and a check for $10 so the P.R.O can have his signature notarized, then you take the signed lost title form, or the returned unopened registered letter, in to DMV and it is as good as a signed title. You may even be able to track down the previous registered owner and just have him sign a lost title form. Just call DMV, tell them you already bought a bike, no title but a bill of sale, what do you do? they'll tell you how..
