Vehicle manufacturers started using VINs in the 1950s, but the new system still had flaws because formats differed among manufacturers. The National Highway Traffic Safety Administration (NHTSA) of the United States standardized the format in 1981. The new standard required all motor vehicles and trailers to have a unique 17-character vehicle identification number that consists of multiple parts with specific codings. You can find a VIN on your superbike, cruiser, moped, ATV, dirt bike, and even (the occasional) electric scooter.
Some racing motorcycles may not have a VIN as they can’t be registered, but if it’s street legal – you should be able to find it.
