What rim width do you have on the rear of the bike? The 900 Monster has the 5.5” rear rim which was originally fitted with the scarce 170/60 size tyres. You can fit the 180/55 on those, but for 190 or 200 width tyres you really need a 6” rim.
If you’ve got the 4.5” rim you are probably already at the maximum rubber at 160.

ETRTO manufacturer parameters allow + or - 3.5% and it's very difficult to allow a fixed value into your calculation. In practice the ride height is an average 5 to 6mm.
I'm really boring on tyres as they've been my job for 34 years...
