I got a question for anyone knowing how to decipher the serial number on a Yamaha Moto 4 200. I bought it for my brother from a friend of mine and he and I are unsure of the year. I have the vin but not sure of which letter or digit stands for the year. Any info would be great.

 

My cousin has a 86' moto 4 200. Im not sure what other years that model was out.
