hey not sure if anyone else knows this but the rear signals can be shortened drastically,to do this is follows.take the piece that is pressed against the rear fender and the outer part of the signal(its almost like a spacer)remove it,put the signal back on and put the spacer piece on the inside of the fender and bolt it back up,no need to cut you can always just swap it back to stock if needed,i've done this on zxr 1100,zx12r,6r,9r,on the zrx you can do it to the front as well,its really clean and looks factory.any questions e-mail me i'll help you out,
