There are two options for the rear brakes. You can either keep the original calipers and re-drill the original rotors to 5-stud, or you can adapt MS123 calipers and rotors to your swingarm. The former is pretty self-explanatory (I choose that path with my MA61), the latter I can't quite recall the details but others have done it and I'm sure they'll chime in.
You'll need a 5t press to get the wheel bearings out. I've heard of people bashing them out after a considerable amount of time and effort, but I'd rather pay a workshop a few bucks to press them out.![]()
