I once checked some of the VIN numbers on photos of some of the smuggled big-bore Japanese bikes for sale on 58.com and weifengtang and most of them were wrecked bikes from the US that had been advertised for sale on breakers' websites in the US. Not saying that some of them weren't stolen but I reckon most of them were salvage bikes that had been purchased legally, taken apart, and then shipped off to China to the notorious port at Jie Shi where they are reassembled, fixed up and tarted up to look all new and shiny. To me, it's all the more reason not to ever buy one.
