Hi.
Does anyone else hate the locked rear diff on z800ex?
Would the diff from the new z1000 fit?
Or could the front diff be fitted on the rear,? Probably a stupid question, but if I don't ask I don't fins out.

The rear gear case is a typical design for most off-road vehicles and works fine unless you need it for extended on-road or pavement uses and/or turf/greens applications. In the US, there is no option for one with "Turf Mode", however in the EU they have the option of a locking differential or one that has "Turf Mode". This would be a welcomed option in the US but as I understand it, we can't even order one for use in the US. That may not be 100% true...but it sure would be nice if someone could find a way to have then sent here. As for converting the front for use on the rear...not possible as it wasn't built strong enough not would it operate in the correct direction. 

Thinking there are a number of people on this forum who don't live in North America.  I wonder if one of them could find the part number for the "Turf Mode" diff and post it.  That would at least be the first step in trying to obtain one.

Probably just Google CFMoto Parts in any EU country. Likely to have a web site. Yeah simple enough.. below is the 2021 Z800 auto-diff. #1 is the part number. Likely 2500 USD though...just guessing. Also remember that depending on the year the parking brake changed in 2018 to the outer wheels so if yours is 2014-2017 this one may not work.
