how is it a possible that a replacemnt frame has no vin? not possible. any frame made would be stamped with a vin to determine year and all that. no vin= no title. no title= no registration. any frame mad by a reputable manufacture will have a vin. why do you think that people have so many issues registering their china made atvs, and bike? because the company is shady, made up a vin, stamped it on there and sold it with it being inspected for quality to be sold in the USA.
