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:
the bolt heads are 8mm for the 6mm shaft size and dished out. They also use some special fasteners for some parts of the bike that the Jap bikes dont use.
