I did not impact or do anything to damage them. I didn't ride my K-bike nearly as hard as I do the FJR. Half a liter of oil per fork. It failed enough to have a small hole that sprayed like a mist when working the forks. You can defend all you want, but I am telling you a real world experience. The telelever system, like other forks, can have failures over time. Also depending on the year of the bike, they used multiple manufacturers, which use different fork seals. Must not be a perfect system if they changed them.
