Has it got a VIN no. on the headstock? That'll tell you if its a honda or not. There looks to be a mix of chinese and original honda parts. The tank looks chinese (and the breather cap used as a fuel cap is definitely not honda!). The bars, switchgear and bar clamp look chinese, so does the exhaust. The wheels aren't original honda ones either. The indicators aren't honda. The engine number should tell you its origin, if there are stars in the engine number its definitely chinese.
Without seeing more its hard to tell, if i had to guess I'd say at best someone replaced all the worn out honda stuff with bits off a chinese replica, maybe made one rider out of two bikes, one a worn out zed and the other chinese replica.
