No ntn has ever failed in the same premature way as skf .... Includes zero endfloat on a 644 built in the UK.
Find a picture of a failed ntn out of a berg... There are none
Watch the fink desert race docos on YouTube. This is the test environment orangeberg was in to come up with the observation of ntn handling lower end float.
Wot runs with high gearing for hours, no green Laning
The code on the ntn specifically indicates special design to accommodate high axial loads and misalignment.
As for the ntn being dropped, even ktm au doesn't know anything about that. It's also still a current part number for 2021 model ktms.
The fact that skf need at least 0.7 mm to survive is proof they are less able to handle axial loading ... Nuf said, I've used both and prefer the cheaper one that lasts longer .
