Is the shorter straight portion which makes them richer off idle when compared with the same stem diameter.

Yes, Smaller straight section would be richer, but i'm talking about the 1st of the 3 tapers on those needles, and for sure the the NOZx and N1Ex have a richer 1st taper than the Kawasaki N3Y/Wx and the NEC/Dx needles. The NOZx needles have a longer straight section in particular and this adds to that needle series overall richer feeling at lower throttle settings.
