The 200 is completely different and you cannot easily make a 200 out of a 125/150. I have greatly enjoyed your ride reports, wine and all, and if 50 kph is enough, you don't need a 200 but if you set your sights further afield it would be a much more interesting ride on the larger bike. 50mph for the 125, 55mph for the 150 and 65 for the 200.
On the other hand if you get a 125 like the one you have been riding and then decide to get ambitious it should be easy enough to move up to a 200 with all those kids wanting 125s.
The Rally is a collectors bike and fast while earlier bikes are pretty but gutless. The P series are work horses with better brakes and suspension and suited to daily use. Luckily Indian Stars are off your radar.
Size does matter. Speaking as a man who has attained the giddy heights of 200 size.
