Front end vibration and Wilbers

[KatW]

My 800 seems to have started a horrible vibration from the front end when reaching speeds around 130/140kmph. I can equate it to riding over a rocky road.
I had Wilbers progressives installed a week prior - I'm wondering whether they could be the problem?

I don't seem to remember getting awful vibrations at that speed without the Wilbers since I tend to cruise at those speeds on the open road for long distances.
Or maybe this is normal for the 800 with or without the springs and I've only noticed it now?

Anybody have experience with front end vibration?
