LC 125/172 DRUM Runner Engine in a 2005 NRG Power?

Just wondering if a liquid cooled 172 engine will go straight into my Piaggio NRG Power DD without any problems. Are all the connections the same? Mine has a disc on the rear but this L/C 172 engine has a drum, how would i go about getting that to work? either drum or disc

 

No it's completely different, the brake isn't a problem but the wiring is all wrong, engine mounts wrong but people bodge them in anyway.

 

yeah i done abit of searching and sounds like effort haha, im just looking for a cheap aerox/typhoon/nrg etc etc to get me around for now
