To determine the year of your Yamaha 4x4 quad, locate the Vehicle Identification Number (VIN), usually found on the frame or near the engine. The 17-character VIN contains a specific character that indicates the model year, typically the 10th character. You can also check the owner’s manual or Yamaha's official website, where you can enter the VIN for more detailed information about your quad's specifications and year.
The 10th digit is the model year
Your best bet it to call Colt.
