Aerox 70cc

Hi I have a 2004 aerox, I was wondering what engines from any bike would fit one of these? Thanks

 

i think aerox engines might fit straight in, to my knowledge no other ped engine fits straight

but seriously youll get pretty much any engine in a bike if you try hard enough

 

Cheers mate, I was thinking of putting a gilera runner engine in, aerox's are liquid cooled, would I have to put another liqiuid cooled engine in? Or would it work with any?
