In the UK, we have the DVLA, who keep records of past owners of bikes, cars etc. Upon payment of £5 you can request a list of the past owners and where they lived. needless to say I got mine back and next year, I'm going to revisit all those places the bike was owned starting from the yamaha dealer who happily, is still in exsistence
