Check the VIN codes. VIN = Vehicle Identification Number. Typically one of the letters or numbers will indicate what year it was made. A key to the VIN should be easy to find online. Type in the search "VIN" whatever the manufacturer of the ATV is, such as "Honda" and "data" or any combination of these. I tried this search method on Google to research my Cadillac's VIN and got an answer in the first batch of search results. The 10th digit of a 17 digit vin # is the year .
