No...the V.I.N is the actual unique number or the "serial number" of cars or bike. And every other part in the car/bike has its regular part number, when they manufacture your motorcycle or car in japan, the manufacturer has part numbers on almost anything that is put in the vehicle, and all those part numbers belong to that V.I.N the "Family" or that bike/car. So the parts in the car or bike are linked to that one unique V.I.N i.e serial number of the bike/car.
So for example when in California street racing, when cops bust street racers, they run their engine part numbers through the system, and 99% of the time they catch racers with stolen parts, those part numbers link back to its original V.I.N (serial number, unique number, the original vehicle it was put into), and that's how easy it is to figure out that the street racer had a stolen engine, and that parts in his car were from another car.
So if someone stole your 1000RR's radiator, and some racer on a cbr 1000rr in cali got booked for street racing and cops ran his radiator part number and it matched your V.I.N, that guys is ****ED! as long as your bikes radiator was reported stolen. and as long as someone on the other end runs the part number...if its reported stolen, that person with the stolen part is done for...reason those kids get booked in cali, is because they are stupid, they just steal parts from one car and sell it to someone else who has no idea and put it into theirs, all locally too.
Professional thieves, take the whole car, whole bike, rip it all to parts, destroy the VIN and part numbers, and replace them with fake untraceable numbers and VIN, and sell the stolen stuff with never used numbers, usually in 3rd world developing places where no will ever check.
