How do you tell the year of your Yamaha motorcycl by the serial number?

To determine the year of your Yamaha motorcycle using the serial number, locate the Vehicle Identification Number (VIN), typically found on the frame or engine. The 10th character of the VIN indicates the model year; for example, "A" represents 1980, "B" for 1981, and so forth, cycling every 30 years. If your motorcycle is from 2010 onwards, the letters will correspond to the years 2010 (A) through 2019 (J), with 2020 starting back at "K." For exact details, consult Yamaha's official resources or a detailed VIN decoder.
