Great advice the seller, won't even give him the ownership yet he is going to fork over the cash +, +, +. Then you recommend the OP commit theft by keeping the bike.. I certainly hope you don't follow your own advice.
OP you will "likely" have no issue getting an ownership, via an affidavit. As I said earlier the only "possible" hiccup, i can foresee is if the wife never gave hubby the OK to sell bike and she wants HER, bike back. If they are in a marital dispute this could get tricky. You have NOTHING to prove, you bought the bike and how much cash you forked over to the husband. She may not want to give you anything to get it back she can simply call the cops tell them you have HER bike. Cops come, they take the bike, and your the one left holding the bag. Although chances are if you show the cops the texts they would just say "give her the bike and we won't lay a charge".

Go back to dudes house and get your money back +gas, +time, +interest, +headache and stress, +your not going to cave his head in! Why you just didn't do that in the first place? Forget all that other crap......you got robbed! And I would keep the bike.
