The handle bar issue should be fine I reckon, the KG176 has a quill stem and a threaded headset which has a load of parts above the HT. I also can't get it down very low as the HT is so short it bottoms out before it's really slammed. There's effectively 60mm from the top of the HT to the centre line of the stem just now. I imagine that with an integrated headset and maybe one of tester's bearing caps I'd be fine.
As far as my shonky spirit level measurements, the stack is 524mm and the reach is 391mm. Those are both to the centre line of the HT where it intersects the top of the TT.
