vespa px

I think about to pump up a little my vespa PX 125  '97.
I will drive without any problems and safety.Only for use daily and not for racing...
I was thinking for buying a DR 177 cilinder, dellorto 24/24 and a sito + exhaust?

 Is this a good combination and also "plug and play"??

it's only for drive a little bit faster and with no problems. is it enough only change this articles or need i  more changings  or have you any other suggestions ( combinations)??




its a good combo, but would add. the  longer clutch gear with 22 cogs
