Super 8 50 2T LC2U91000 upgrade to higher cc

[KymcoSuper82TDutch]

Hello I have a Kymco Super 8 50cc 2T which runs at the moment with a topspeed of 60km/h its stock, can I upgrade to a bigger cylinder and if so what is the biggest I can put on and what else to upgrade the performance? Any useful help is very appreciated, Kymco is located in Greece where parts are hard to find as well as good mechanics in my area.

It's truly not worth the trouble to upgrade a 50cc to anything useful.  You won't see much improvement at even 70cc or 80cc, and the bottom-end will give way shortly afterward.  The result is usually a broken crankshaft. The next step up in useful performance is about 100cc - 125cc, and that's a much bigger, stronger bottom-end that will have a good service life.  Kymco parts are not  problem in Greece.  Order from https://www.motorradwelt-auer.de (Germany) or https://www.azmotors.fr/ (France), for example.  From Greece, you can just go parts shopping on a day-trip, you don't even need a passport!
