Help me)))

Hello, I have a Vespa 50 XL, want to make a tuning to 100сс 120сс , maybe someone can help tell which parts of the better ?
That would not expensive work.
Tell me please

The world is your oyster!

I have a stock 110cc Malossi kit for my daughter's 50, with a minimal amount of work to the bottom-end and a 1/2 decent exhaust it isn't a bad stat, but you really need to decide what you want to do and how much money you want to spend on it.

You could also have a look for a PK125 engine complete and keep the reliability of standard and still have a good increase in performance.
