5cm ~ 2 inches!
George,
I lowered a 2010 1090RR about 3/4 inch (~2cm) front and rear.
There are impediments to going lower. Some have been mentioned, but the structure of the 1090RR fork is also an issue. If you look at the attached photo you will see that the fork tube has two diameters and that the lower triple clamps on the larger diameter. The yellow arrow pointing down shows the step change. The yellow arrow pointing right is the bottom of the larger diameter and that is as low as I was comfortable taking the triple.
The rear change has to be made using the correct ride height tool.
Hope this helps.
Chuck
