Like many legal passenger vehicles, Yamaha ATVs have a 17-digit VIN or Vehicle Identification Number. These characters can include numbers from zero through nine and capital letters from A through Z. They never contain I, O and Q, to avoid confusion when verifying the VIN. The position of each letter and number identifies something about the machine, from the location of manufacture, to the year of manufacture and the model. The VIN is on the lower end of the frame, and finding it should take only a few minutes.
Park the ATV on a flat level surface and set the parking brake. Remove the key from the ignition.
Locate the VIN digits on the left hand side on the lower part of the frame by the footpad. Look for a 17-digit code stamped into the frame.
