As you know, I have a 'scooter' ... Vespa 250cc back in TO. Brought it brand new, has only 300 km on it ... it's a toy for me as I prefer the safety of car.
If the reason is just to get from A to B at a leisure speed, 125 cc bikes are good enough. Irish and I have seen plenty in Taishan where they carry everything they can think of ... chickens, rice sacks, construction 2x4s, propane tanks etc etc etc.
