There's a nice upside down ktm forks and i could get them really cheap, but i don't know is there a chance fitting them on XT??
Does anybody have a clue?

Offtheroad.de sell yokes for both the R and Z to take the 48mm WP forks as fitted to most recent KTM's. They're quite pricey, but that's what you pay for something that bolts straight up.

As for trying to fit them using the KTM yokes, I don't know, but I bet someone's tried it.

hi, with a bit of work the ktm triples and fork/wheel brake setup will fit the tenere [at least]. i don't think the xtr is that much different.the standard ktm 690 forks are 25mm shorter and less damped than the usual exc fork. so anyone racing a 690 changes to the competion version thought the standard 690 units will be a vast improvement over the simple yamaha forks.

jmo, flatlander and myself have carried out the conversion. checkout http://www.xt660.com/showthread.php?t=14756&page=2
