Ignore him, eventually you'll get used to his nonsense rambling. The bike is perfectly fine as it comes out of the factory and there is nothing about it that makes it unsafe. But according to kawdog, the ABS will kill you, so it has to be removed, and you have to get iron rotors or mythical copper brake pads (regular EBC HH pads, for some reason he believes they are some sort of gift from the gods).
By the way, why don't you get a used one? Get an older Versys, decide if you like it or not. That will let you know if just the addition of ABS would be fine (leftover 2014), if you need the newer '15 or if the Versys is just not for you.
Toad is just a bad spammer and generally wastes owners' time, money, or risk their lives without thinking twice. He may be an immature 16 yo or younger.
These additions are mostly not tied to this supermoto tourer model but are general changes to ANY bike you get to customize it to you.
Things you will need (not all at once) will be crash bars, rear rack, dual or air horn, front fender extender to keep nails from giving rear flats. rear fender to keep clean easily, lowered pegs (if you can touch the ground) or lowering kit (if you can't touch the ground), some sort of seat alteration/pads/cover to make it more comfortable, new tires as the stock ones will wear bad quickly, a trunk w/reflectors to carry things you use commonly (on rear rack), unless you get a 2015 - a different windscreen that has some coverage, and copper bit EBC brake pads if you like to stop.
Extras may include LED brake flasher light, hand guards (and extra bar end weights to compensate for hand guard weight), heated grip elements with dial controller, grip buddies if you are 6' or taller or have big hands, electrical outlets/charger wiring, charger, portable air pump/flat tire kit, extended mirror aluminum fixtures, a centerstand to work on your bike or check your tires anywhere, a shock sock to keep it clean, if you are heavy - another shock possibly, after you screw up your first chain - a DID gold x-chain and sprockets, a complete chain guard (included in some rear fenders), voltage meter light, radiator fluid temp gage, and then by the time you have got all this customized to you, you will need a valve adjustment in your first major tune up (around 10k miles or so - but it will run 'fine' after that.) The list goes on (including garments you wear) in more detail, but those are the highlight changes most may consider if they know about them or read this site some.
Personally, I do not need saddlebags, gear indicators, steel brake lines, or several other things commonly sold, but everyone is different.
Safety First! ymmv.
