Thank you for all your replies.
That's the information I was looking for.
I'm researching to purchase the ADv bike and so far came up to ether F800GS or 800XC.
I'm aware about many details on these two bikes. I was interested in performance of the stock forks under "normal" riding. Nothing major than the lite trail or regular paved road. Seems like it works well.
If anyone has more information to share about their personal experience with stock suspension, that would be great.
