Thanks for the replies guys.

Smuggling?? That's bad and I wouldn't consider it.

In Beijing it's next to impossible to register a sportbike anyways, unless you go the fake Hebei plates route. Which is possible with any bike. What scares me about buying a bike here is not knowing what parts have been swapped with chinese parts and what you end up getting. I'm just considering it seeing as I'll be making a trip back.

What I'm concerned with is do I need a special permit or license to import auto parts? Or can I have it shipped to a residential or office address? Also, are duties slapped on personal shipments of auto parts?
