OK the 1100 Kat FE like this one, has the steering stop in the front. It will hit the GS's steering stop which is also in the front of the frame.
Kat 600 and kat 750 are the only ones that will fit in the GS among the kat series bikes. What else will fit ... no clue ... but just be wary of unknown sheite that seems to cover everything under the sun. Such a thing does not exist.
Cool.
