Would anyone know if a windshield for 2022 will fit a 23 ?

[2015 Z Force 800 53/Trail EPS]

That's the old style cage and chassis design so I'm sure it will not fit the 2023s.

That is correct.  The rollcage bar design has changed, no aftermarket (that I know of) for the earlier models will fit the 2023 Zforce Trail because the bars are totally different.  If you want a windsheild, full or half, they are available through the Acceessories catalog for 2023 along with mirrors.

Where is the accessories catalog ?

My dealer had the catalog.   You can find an online copy at:

NO it will not.  Completely different machine.  At the moment all there is, is OEM from your dealership.  I think I am getting one of the first heaters from a company tomorrow for my 23 800 trail 

Ordered a cargo box and side mirrors for the new machine from my dealer, took a little over 4 weeks to arrive. 
The cargo box was a dream to install, two CFConnect clamps and your done. 
The side mirrors were fairly easy to install except that the four  8-1.25mm locking nuts were not supplied, quick trip into hardware store solved that.  Let the dealer know they were missing.
The left mirror went on real easy but the right one was a different story.  Had to run a die down one stud to get the nut on;
suspect a burr on the threads.
