Hi Kean_Lim
I am fairly sure that as the ABS disc/rotor is fitted to the hub of the wheels, and the sensor picks up the signal as the wheel rotates.. I don't think fitting different sized wheels would alter the ABS operation.
That said, you will have to consider the fact that as the wheel is bigger it will have a larger circumference and rolling distance. This will affect your speedo accuracy and therefore the speed at which the ABS becomes active. Although only a small-ish difference it may affect handling. I would suggest going to your local HD shop and speaking to a friendly HD technician, who can advise you in what you are trying to achieve, and the issues you may face.
