I supose if you could get a decent used one it be a good option?

There are not allot of midrange options in China, there are a few 250-300cc options.
It seem it may be possible now to get a 250cc Benelli motard...that be my choice if you can find one.

if they are actuually selling for 16,800 RMB, I rather be in for $2500.00, then holding a used bike that cost more.
