A motorcycle usually has its vehicle identification number vertically on the steering neck. A rider should turn the handlebars to the left and inspect the right side of the frame where the steering head goes through. In some cases, the VIN is on the motor near the cylinder bottoms.
Another way to look up the VIN of a motorcycle is to check the registration, title and possibly insurance card of the vehicle. VINs are important for customers to have when they buy motorcycle parts or if they sell or buy motorcycles. A VIN is 17 characters long and has three sections. It gives insight into the make, model and year of a motorcycle, among other information.
