Chasis wise they are quite different. The engines are very similar, only real difference is the head on the GPX has better design valves & intake so is more powerfull (10hp). I'm not sure if a GPX head can be bolted straight onto a GPZ engine, nor if the CDI / rev limits are different, but most likely are interchangable.
