Kymco agilty 125cc engine in my 50??

[agilitycity50]

Hi I wana ask the question when I hit 17 can I put a 125cc engine from a kymco agility 125 into my current 50cc kymco agility? Would I need any new parts or could I just put it straight in?

It can be done but from what I've read you'll always be fixing something on the 50 that wasn't spec'd to hAndle the stress of being pushed by a 125.   Best upgrade for a used 50 is a used 125.  And yes, more than the engine will need to be swapped.

As much as i've understood the only difference between the 125 and the 50 is the placement of the mount, so the stress probably wouldn't be that much different.
