I was at jiaoji lu and got a few quotes.

a 125cc without plates is 2000 with 200 for plates elsewhere.

50cc bike with blue plate at bike plus ( plate price of 900 - 27000 depending on A B C

150 cc bike with (yellow plate was 53000 - 7000 rmb) depending on A B C

I was thinking of buying a bike but was told I need a license to buy so that he can tag the plate to? is that the case?

Am I better of with a cheap bike with 200 blue plate?
And also if I want to but plates, what plate should I get.

I am ok with the 200 fine or 700 to get the bike back / confiscation etc so long as I do not get into trouble.

advise is appreciated please.
