The Vehicle Identification Number of a motorcycle is usually located on the steering neck, but on some motorcycles it is located on the motor. In all cases, the Vehicle Identification Number is etched into the metal frame of the vehicle so that it cannot be removed.
A motorcycle's Vehicle Identification Number is a 17-character code that is unique to each vehicle. The VIN contains information about a vehicle's manufacture and history. By locating the VIN on a vehicle's frame or motor, a buyer can use this information to request a report on that particular vehicle from DMV.org. The VIN is also printed on vehicle titles and insurance documents.
