Hi,
recently I had 30.000km service and I asked them to replace tires as well.
Service consisted also in changing fork oil.
I have now Haidenau K60.
I went for a trip next day after the service and noticed on highway when I go beyond 110kmph, bike starts to be very unstable. Front fork starts to shake semi-violent (left and right). If I slow to 105 .. all is fine.
Before this I used to go 160kmph with no drama.
What can be?
