I don't mean to tread on anyone's feelings, and being new here I'm a bit hesitant in going all out on this - but I feel very strongly about this topic in general.. I am amazed at how many people are concerned (not just here) about a forum potentially asking that sellers supply a VIN # for bike sales and are worried about their 'privacy'. When you ride your bike in public, you are exposing your tag # to 'anyone' who is behind you, or happens upon your bike parked - anywhere. All these 'bad' things you're worried about happening by posting your VIN# in a bike forum, could happen ANY DAY when you take your bike out - even more if you are in a apt complex, or park at the street, and constant access to your bike to the public is available.. (counting down to the 'but I park in my garage' reply - doh..) Not only could they just walk up and record your tag anywhere when you are out and about and not on the bike, but your VIN# as well! What's it going to get them - your name, your address? When you got the bike? That's good information to 'share' if you're trying to sell a legitimately purchased vehicle of any sort.. If you aren't selling - again what are they going to do with that information?
Lets go over this logically.. VIN #'s are all unique.. It's like the DNA of your vehicle (ANY vehicle), it cannot be copied (and used purposefully at least!). With your VIN# in hand - they cannot get a vehicle registered if they tried to dupe it to another bike.. (Duh, it's already going to be registered to a vehicle!) And at best, it damn well better be the same make, model, year, and color! Oh wait - they did and 'somehow' suddenly you have to prove your bike is yours? TITLE or the last 'transfer' of that title - ALL on record at the DOT.... History of Sale.. In fact - trying to register a VIN# already registered will likely lead to security showing up at the DOT teller window to talk with them.. You have to provide real world personal information to register a vehicle at the DOT, you know.. Like - a License???

So - is the worry here that someone is not only going to scam your identity - make a fake ID, walk into a DOT office and provide a false or copied VIN#, to register a stolen (or totaled via insurance) vehicle - so they can legally get insurance???? Chuck Norris doesn't even have balls that big (or is that stupid..) Are there criminal idiots that try that? Positive! Success rate tho and frequency?? Stolen bikes get parted out or sold overseas anyhow, trying to legally register a stolen bike in the age of the 'net at this point with cities, counties and states sharing info - really?
Believe me, working in IT security for 20+ years - I am just sensing a little paranoia here of the 'unknown'. Like when people freak out about java update popups on their PC and don't do them - but will go ahead and open every damn email they get from unknown people, and click every link in them to 'see' whats there.. (Derp!)
If a potential seller wouldn't supply you the VIN# or made it incredibly difficult for you to get it "oh, you gotta come to the bike to get that bro" - what would you think? (I'd think they had a ins claim and are covering up the bike history, is what I would think - or worse, it's 'hot'). If you are that worried about privacy - just sell your bike to a used dealer and call it a day? Why bother selling on a fanatics forum at that point??
To each their own (including your level of personal privacy) I just get a bit alarmed when I see Fear being spread for no good reason (The IT security world mimics real life in this respect - I see it EVERY DAY from uninformed folks). Giving a VIN# is not like accepting a Nigerian email scam.. 'Requesting' that for our forum is a good sign we don't 'want' criminals here selling hot bikes, and that all bike sales here are on the up and up.. Unless of course - they aren't?
Lets also not get started on the concern about pasting pics of vehicles and covering your Tags.. That's the biggest sign of Egotism I can think of in the vehicle fanatics world online. (oh man, I don't want 'anyone' to know who I am in this worked up Honda!). Unless of course you 'are' that person out doing 150 on the highway (not likely a Honda!

) with cops after you, and you're constantly posting youtube videos of your exploits (law breaking) for all to see of course.. Gonna defend your law breaking by wanting to be 'private'?
