[CBR250R]

For me - I would be more interested in an aftermarket exhaust merely to save weight. Granted, it is an expensive way to save weight - but farkles aren't meant to be completely rational anyway. The bike would look better with an aftermarket exhaust too (in my humble opinion). I don't care if an aftermarket exhaust is even quieter and produces no change in power - I just want 10 lbs less on my bike. Add in a Shorai battery and I might be able to reduce the weight of the CBR250R by 15lbs.
