This is a great affordable accessory for your Z125!  While there isn’t a lot of room on the Z125 for a passenger, if you do take one, this adds an extra spot to hold on.  With its heavy duty construction, it also can be very handy to use when positioning your bike in tight spots or when loading and unloading during transport. Its very easy to install, going between the tail light bracket and the frame with the included 4 bolts.
