Kymco K-Pipe 50 rear or front sprocket and chain

[kalle.si]

I just bought a used Kymco K-pipe 50, and right now it's going too fast to be legal (I live in Finland). under me it goes about 70km/h and from what i heard from the dude who i bought it from, he had only changed the carburetor. What i need is to change either one of the sprockets to make the bike go somewhere around 55km/h. Do any of you have links to smaller front sprockets or bigger back sprockets and chains that fit with them? Thanks!

Sorry. Can't help you.
Maybe someone will point you to an Asian supplier.
BUT, you win the Donut for having the very first post asking for ways to slow down your Kymco!
(and if you could eat a lot of pastries...that might drop your speed a few KPH?)
Good luck with your bike!😊
