Ngk

Has anyone used an NGK Bpr7eix in their Z1.

Way to many letters. B8ES or W24 ES-U

I stumbled on this. NGK B8ES alternative plugs. Might be interesting to some.

I use ngk bpe8s, the tip is about 1mm longer, they work great in mine, I also never buy off of ebay as there are way too many fakes out there.

Has anyone ever used iridium plugs in their motorcycle? Are they worth the extra money or not really?

NGK BR8EIX

My personal opinion is that unless you are running a high output/turbo motor there is no real benefit for the additional expense

I ran these in one bike for a while.  They worked fine.  Wound up removing them because I realized they are resistor plugs, and I already had resistor plug caps.  No need for two different resistor elements in the circuit (even though the bike didn't seem to care.)
