greetings...
the k75 hub is 4 lug bolts and 1 center bolt...
the 1200 hub is 5 lug bolts and 0 center bolt...
so you would have to fabricate an adapter... before making an adapter put a measuring take acrosst the swing arm at the leading edge of the rear tior... that will tell you how wide a tior you can run without machining a new swing arm...
so... measure that and report back here...
