"Chopper effect"
Soft and hard at the same time, worst feeling there is when riding a bike +++ lots of weight transfer when braking (because so much sag in the back), so you end up closing compression in the front to avoid that but it only makes it worse.
That's just an example, I'm not saying it's the case here.
Only measuring sags can tell what's going on with his bike.
Thanks this ist a good hint. And tracable for me. Because of the known 75kg KTM Standardrider it is a good idea to increase the preload at first :L
