Personally I think its a bit lame to make it look exactly like something that isn't that is "in-line". You're posing at that point to be something you aren't because you don't have it, can't afford it, or whatever. .
I'm all for making it look like a MotoGP bike, a WSBK bike, a whatever - including the exact same colorway. But if you're entire reason for changing a bike to make it look like the more expensive big brother or something screams lame to me.
I mean at least the rice rockets that people modify have a distinct different style (however gaudy it is). . I guess its also like the difference between those who are truly rich and those who want to pretend to be. I know people who are wealthy beyond belief and they strip the numbers off the car (like taking the S600AMG banner off the car, and then those who want to look rich who aren't and who make sure they take the smaller number off and put a S600AMG badge on. As I said - its your bike, you are free to do what you want just as every one of us is free to feel how we feel. .
