You can buy Talon hubs, however they do not make rear ones for the XT. However, you can buy one from KTM 690 and fit it to your wheel. There is a trick, though. The LC4 engine of the 690 is narrower than the XT one and the hub has to be off center with a flange machined to fit the brake disc at the proper place.
The benefit? Nice liking and probably 2kgs weight saving. I believe Pleades has such a set on his.
