PX150 on a Acma 1956


I want to adapt a PX engine on my Vespa Acma 1956. Someone told me I can only adapt a LML 3 Port engine because of the 8" wheels.

Can I adapt this one?


With the Adaptor shock absorber above and the Adaptor engine rocker.

Does anybody has some experience with this? Or maby a website?



Hi dude


I guess you´ve got a wrong information.


Basically you can mount every type of px engine in combination with your acma.

The only thing you have to modify is to mount a engine adapter.

It´s item code 63003000.



Do you want to go with 8 or 10 inch wheels ?
