Dealing with a lien?

[Porkchop]

So as some of you have seen, my friend is selling his bike. He got trapped in the whole Suzuki credit card thing, and is just treading water right now on the thing. I felt bad for him, so I decided to help him sell it. Well we have seen a couple lowball cash offers, but nothing that he is comfortable with. His balance left is about $4400, which is pretty ass backwards. He is pretty comfortable with paying about $400 to get rid of it. Today I had a guy email me about possibly transferring the lien to him. I'm not very versed in stuff like this. Isn't that technically impossible? Doesn't this guy have to go out and get his own loan, and bring us the cash? Or can the lien be transfered barring credit approval from suzuki financial? I know its probably a pretty stupid question, but I've never owned a vehicle bought on a loan.
