Question for the guys that ride Euro bikes????

I know there are a bunch of you guys that ride KTM so here is a question that I've wondered about for some time and never got around to asking anybody about: When I go and buy a fasteners kit, there is always a separate box for KTM dirtcycles. Why is this? I would have thought that they would be metric fasteners just like the Jap bikes?? What am I missing? Thanks in advance. N-edge :thumb:
