I have a vespa primavera 50cc 2t reg. 2016. I would like to change the engine in it to a 125. Is this possible and has anybody any advice on doing it please? Thanks
engine mounts different, shock mounts different, loom different unless its a 2 stroke 125, length of head aginst the frame clearance different, and the re-reg with dvla, inspection, re-classification etc etc.................. For what it will cost and the grief you will have, just sell the 50 and get a 125
