Moped buy

[DrMoles]

I want to get in to riding mopeds, i had a motocyle. But my question is what are the most common problem on a yamaha areox and what should i look at when im buying a areox?

I want a 49cc but tune it up to like 70cc and idk really about the years but i think i would like a 2 stroke

Okey now i know but what are the main things to look out for when buying an areox. Like broken parta and stuff.
