You would be taking a serious risk if you were to take the bike without having the lien released. It might work out just fine but the seller cannot transfer the title until the lien is released and you would be paying serious money with no guarantee that you will ever legally own the bike. I wouldn't do it without having a clear title in hand. You might want to investigate how long it would take for the release to be filed and then if are willing to hang around until everything falls into place, you would be good to go. Money can move around pretty quickly these days with bank transfers, etc.
