How to tune a Sym Symphony 50cc, 2022 (4 strokes)

[mirkoy2k]

Hi, I'm new in this forum, I have a Sym Symphony 50cc 4 strokes. I would like to boost it, make it go faster, since the top speed is only 60km/h. What should I edit or add? I never made any changes. I saw, in other forums, that you can add a clutch and a variator: but will it affect the engine, in a long time? And how much would the speed change?

I'll say it straight, dont bother get a better and bigger bike.

If only I could get one just turned 15 and the limit age to get a 125cc bike here in italy is 16, I guess I'll wait a year but I want to ride this bike faster since I'll sell it when I turn 15
