I was seeing a biker girl. she had a 125 that she was not using (she had a big bike etc) I had never ridden, so I paid to get it insured and on road. few months go by and it's my birthday. she hands me the keys and documents, gets it signed over to me. huge gesture, I said are you sure you don't want some money for it. I didn't want it hanging over me as a debt if you know what I mean. she was cool, it was a present. ok so we split up about 4months later. I give her all her things back that she asks for. we don't really discuss the bike and she doesn't ask for it back. another 6months past. I have now passed my test and I'm ready to get rid of the 125 (sell it) we haven't spoken since break up but should I get in touch and offer the bike back? shes a friend of my sisters, who thinks I should be offering it back I'm not sure I should be stressing over this though.
