Motorcycle title help?

i bought a bike a long time ago when i was young. i had to have a co-signer. shortly after (about 8 months) she filed bankruptcy. the bank would not accept payment or talk about the loan while it was in limbo. when it came out roughly 3 months it went straight to collections without me knowing. i have hung onto the bike long enough for it to be removed from my credit. the bike is in my name but the bank still owns the lien. i want rid of this bike but i think they could still do a repo on me. i just got this off my credit and i dont want to mess it up again. what do i do?
