Zip 125 / 50 frame

Hi can anybody tell me if the zip 125 frame is the same as the zip 50 frame in terms of engine mounting?

 

aint u gena need one of dem ridiculous multispangle subframe things mick?

 

i no the 50 frame a 125 bolts stragit in just alittle grinding but the 125 zip frames u cant put a 125 2t engine in it as the down tube on the pipe hits the frame

 

I think youve got me mistake.

I know 50 frames like the back of my hand. Mick-T they'll take your 2 stroke lump no trouble.


My question is about 125 (which are 4t) frames.
We want to get a 4t 125 lump into a 50 frame.
I know they have different subframes, but is the actual frame the same?

 

o ok sorry i fault u wanted 2 put a 2t engine a 125 4t frame soz
