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
