Thanks JMo and thanks zewl!

Some more details:
The upper for crown has been designed specifically for my motorcycle and the 690er WP48 fork. This means, it has been quite expensive (not at all cheaper than OTR complete set which is also very nice and black already).
It fits the steering lock (front wheel heading straight when locked). The manufacturer (a major Austrian WP distributor) might be happy to produce some more of it a bit cheaper, since they now have got the CNC machine data feed. Do not know.
Also the new crown utilizes KTM handlbar mounts bolted into the fork crown, no longer needing a big bolt with some big hexnut below fork cron where it is a pain. So, easy handle bar clamp change and usage of stock KTM handlebar parts, even they provided two mounting positions as can be seen in pictures.
Lower fork crown needs a new shaft fitting the Tenere steering head. They also manufactured it and pressed it into lower crown.
Fork mount, axle, wheel parts are fully KTM compliant. Hopefully (yet to be tested) we can even use KTM 690 stock fork setup without change of travel. This would be perfect. In fact, stock suspension setup appears to work quite will, but I have not yet ridden it. These things will happen in February earliest.
I was extremely lucky buying the KTM fork in perfect condition with axle, crowns and everything for a ridiculous price. Otherwise it would have been too expensive.

Actually, I have previously been riding KTM for several years and I used to like it, apart from some engine damage. I am very impressed about the new 690s that I have not yet ridden but would like to. Nevertheless, I also like the Tenere and my WR, so to me its just a matter of coexistence

Kind regards, Phil
