Hi Anne,
Not sure if this helps:
2006 Z1000 Clutch Lever: 46092 46092-0003 LEVER-GRIP,CLUTCH
2006 Z1000 Front Brake Lever: 13236 13236-1337 LEVER-COMP,FRONT BRAKE
2006 Z750 Clutch Lever: 46092 46092-1162 LEVER-GRIP,CLUTCH
2006 Z750 Front Brake Lever: 13236 13236-1337 LEVER-COMP,FRONT BRAKE
...looks like the brake is the same, but not the clutch. Note this is the S variant of the Z750, but it should be the same.
This may be handy:

Cross-referencing the lists gives a few possibilities you can try with Pazzo, I have marked these in red (i.e. they appear in both lists).
Note: The US Ninja 650 is the ER6F, this may be your best bet.
The other ZR750-H1/2/3 is a half-faired version of the old air-cooled ZR-7 from a few years back. I don't think we got them here (we had the naked version) but if you're looking in the US for Pazzo then you may get lucky. The 2008 Versys may be a bit of an ask this early in the year.
...I just had a quick look at the Pazzo site, and it doesn't look good for the clutch lever, none of the bikes on this list are on their list
