So you've got no mechanical experience and you've never ridden a bike and you're looking at turning a very new(ish) factory race bike into a fighter? Man, you should really think this one through some more before you bite off waaay more than you can chew both in the garage and on the street.

I think you should bookmark this forum, buy either one of those bikes, and ride it for at least 3 months to a year before you decide to do ANYTHING to it, including removing plastic fairings. That shit is on those "rockets" for a good reason, aerodynamics. Learn how the bike is supposed to operate before you mess with it. And yes, either one of those things are likely capable of 180+mph, there is absolutely no reason for a new rider (or anyone for that matter) to even attempt to hit that kind of speed, unless you have a death wish. Experienced or not at 120+mph you've guaranteed yourself a trip to the hospital for a while if you bail. You'd be lucky if you weren't killed.
Check out the members builds forums, most of them are late 80's to 90's bikes and every one of them is unique to the builder. Being the guy who was in the same position last year as you are right now (total newb with way more power than I needed, and immediately crashed) buy something that looks good but older & simpler to chop up and not likely to kill you. Just read through stuff on here, don't know what something is? Kindly ask, or my preference is to use Google.
I've been here for close to a year now sense before buying my 06 kawi 636 and learned a shit ton from these guys just from reading and asking my own questions on google, and I'm still not ready to start chopping it up yet. The newer bikes are trickier to mess with, having all those electronics & ram air intakes. In the end, you can make any old bike look and ride much more to your preference than any of the newer crotch rockets covered in plastic.
