Now that's interesting. The manual for my GS says 24.7 psi / 1.7 bar front and 27.6 psi / 1.9 bar rear. Cold, 1 & 2 up.
Yes, lower pressures for the GS version. There is a thread about this in the GS section. Came about because of a similar thing, the dealer applied the Tyre pressures for a 1200 GS. Made for some interesting handling!
