Hey Peter,

The steering stems that I have seen have always been pressed into the lower clamp from the bottom, and they have a lip to create a positive stop. The only ones that are different are the billet KTM clamps that allow you to pull out the stem by hand, when you flip it by 180 you can change the offset as they are concentric.

Just like on these I think you should thread the bottom of the stem for a large M20 1.5 bolt like you have on top, to prevent the stem from ever popping out of the hole because you just have a press fit and no other means of retention. Even just tightening the steering bearings you are putting a pulling force on it otherwise.

By the way I recently bought a slightly bent 690 Enduro frame, just missing the headstock as that has to be sent in to KTM if you want a replacement. Thinking about having a pro join that up with the stem from my old 640 frame and somehow make the Versys engine fit in the middle, la Mr. Quacamole.
