I have alot of carbon on my streetbike... the weight difference in factory fairings, vs carbon is 17lbs. Factory fairing are already light.
The weight savings I have to believe would be substantial.
I am not doing it for aestitics, and yes some do it for looks but I like to keep any of my mods purposeful.
If I am going to take off 60+ pounds, of the front end I would think it would be discernable
