Tire swap
I asked the same question to my local dealer and this is what I was told and saw. You absolutely can put a 200 tire on the factory rim. They had 2 there that I looked at. It does fill the back out a little bit. I honestly didn't notice a huge difference but you can do it. They did say that since it is a tighter fit in the fender and reduces your clearance, that if you do a lot of 2 up riding they wouldn't recommend the change.
