I did the math now to see what my pressure looks like in PSI.
Well, BMW recommends 2.2bar=32.3PSI front and 2.5bar=36.75PSI rear.
With the Metzeler Z6s I used 2.9bar=42.6PSI and it was OK like that.
The new ones (Heidenau K73) start to feel slightly wrong at 2.6bar=38.2PSI, at that 42.6PSI they felt like balancing on blades or so. I may try different pressure front/rear, for now I surely can't go above 38 PSI with the front without compromising handling (I don't know how much it's different because it's now one size larger (120/70) than normal). That's not even 10 PSI above factory recommended.
Ciliegia is a bit differemt because Hyosung recommendations are lower. 1.75bar = 25.7 PSI front and 2-2.25bar = 29.4-33.1 PSI rear. There's no big difference in their weight (167kg/368lbs vs 187kg/412lbs), but the sizes are quite different (110/70-17 + 160/60-17 on Teresa and 110/90-16 + 150/80-15 on Ciliegia). But no way that I could inflate anything under 2 bar.
