    Go to the mooseracing.com website. They sell a kit for reasonable price. Possibly CJdesigns too, but not sure, can't remember. Big on line houses should have access to the mooseracing part numbers too.

    In my experience these can be hard to find over the counter at bearing houses because of a non-std ID or OD, can't remember now (tequila will do that), but its not you and your searching! Edit: oh i see you are in OZ, no wonder you are having a problema.

    +1 on the Moose. My local KTM dealer stocks these.
    If yours doesn't they are in the dealer's aftermarket catalogs.

    I have watched only the steering head video, and I found it to be informative and well presented.

    I don't know about anything else they have done.

    KTM only has one bearing for all models. It should be easy to find a kit.

    Removed my steering head bearings for maintenance and found a rubber o-ring on top of the top bearing, it was like broken and sliced. After a quick look at it and the bearing I was asking myself; why does somebody placces a o-ring on that spot, does it suppose to be there.
    I'm asking this because the edges of the bearing are to sharp for a o-ring to be there.

    Can some-one tell me the contents for only the top steering head bearing?

    Cheers

    Dennis Kirk has the Moose bearings. I just installed some in my 250. It was very easy. https://www.denniskirk.com/moose/steering-stem-bearing-kit.p505750.prd/505750.sku

    Here's a better video. http://advrider.com/forums/showthread.php?t=363572

    In the video, the guys reuse the old race to seat the new lower bearing. Instead, I used a large nut with a 1 1/4 inside diameter that slide over the stem to seat the new lower bearing. It was my first time doing a set of steering bearings and it was a piece of cake.

    The top seal isn't a standard o-ring, it's a special seal, and yes there is a slit in it most likely to help it compress and seal better when the steering head nut it tightened.

    If you buy an aftermarket steering head bearing kit both the top and bottom seals are included.

    It's not the outside rubber that seals the metal cap. I think it's un inside rubber o-rong that seals the bearing-pen and the metal cap under the upper tropple clamp.
    Thanx for your reactions

    I just looked at the parts book, and shows nothing between the metal cap, and the T-clamp. The pic does show a sealing ring between the cap, and the bearing. It is labeled "54601184000 STEARING HEAD GASKET TOP."

    I haven't had mine apart for a while, but I think the seal is so labeled because, as Hipster said, it is not a standard o-ring.

    That small o-ring is in the wrong spot.

    There should be large rubber circular rubber gasket that goes around the diameter of the head tube after the top bearing goes in... Then the metal top plate sits above the bearing under the top triple clamp with the small o-ring on top of it.

    If you look under the top triple, you'll see a small recessed ares where this mysterious small o-ring is supposed to seat.
