As for a VIN, I am speaking of a VIN that will allow a blue plate title. I suppose it may be possible to trail plate the bike, and at least have an ownership for record of title in your name. I certainly would not think this will ever be a road legal bike.
Watch the e-bay reviews of this bike posted above, or go see one in person.
Loose fastners and peeling decals right from the store. That said, for an occasional trail beater it might work for some period of time. I'd still go for a real bike, for $1000 you can find a used XR70, and I'd sure go with that before this thing brand new.
