The Z-90 engine is the same as on the X-90.

The 90cc Z-90 is in some way uncommon. It is larger than other minibikes like a Honda Monkey or a Harley-Davidson X90, but still much smaller in overall size like a 125cc motorcycle.
An adult riding that vehicle looks outgrown to the bikes dimensions. So, one must assume the target group for that bike was teenagers who are starting to ride a bike.
In the move "The Bad News Bears" with Walter Matthaus from 1976 this bike is ridden by one of the main (teenager) actors. If you have a passion for two stroke Aermacchis you have to watch that movie at least once. :-)
