Most, if not all, modern motorcycles already come with ABS braking. For many motorcycles it's also adjustable, for example switching off ABS in the rear while retaining it in the front, for those riding offroad and dirt.
Many bikes also come with cornering ABS, meaning that if the motorcycle is at an angle, the ABS comes in gradually.
Overall ABS is pretty much a "solved" problem right now, on motorcycles 2012+ at the very least. Earlier ABS wasn't that great. I had a BMW F800GS in 2010 and the ABS was horrible on bumpy roads. You basically had no braking if it kicked in.

I'm in South Africa, and most of the popular brands have ABS by default, including top sellers like BMW R1300GS, Honda Africa Twin, KTM 890. This is big adventure country, like Australia. I think the superbikes also have ABS now since about 10 years ago.
