RE: CBR600RR Exhaust on CBR600F4i
That must be why the RR performance is so much worse than the F4i then?
Longer pipes=more weight. Higher CG=worse handling, Weight hung out back=hight polar moment of inertia, slow direction changes.All bad. Looks great...hurts performance.
You cant put all the sound and emission conrols stuck inside and snaked through the chassis for long and even now you can't do it efficiently. The Hayabusa could neverdo it, the GSXR cant do it anymoreand soon the 1000RR won't be able to do it. Fashion is just as important as performance when selling motorcycles. I like the underseat exhaust alot, but it definitley slows a bike down.

Maybe that's why the Gsxr1000 makes 8% more power than the 1000RR.
