How do i know the year of artic cat 400 ATV 4x4?

To determine the year of your Arctic Cat 400 ATV 4x4, you can check the Vehicle Identification Number (VIN), which is usually located on the frame or near the rear of the machine. The VIN contains a 17-character sequence, and the 10th character indicates the model year. Alternatively, you can refer to the owner's manual or contact an Arctic Cat dealer with your VIN for assistance in identifying the year.
