They're both wholesalers, neither is a retailer.
The wholesale price of those is actually high for a Chinese made motorcycle.
I would not order one unless it is being brought over for testing to make it legal.
If you believe that there is a market for these then its an opportunity to import and sell them.
Its not a scam....distribution cost does add to the retail price.

You could get one as a test bike and then only can register it for a year to make it legal, as in get it EPA certified. The factory can certainly make them to meet EPA requirements, but you still have to go through the certification process.

If you had a scrap title for an old one then you may be able to beat the system, however that in reality is a felony.
