Fuel economy estimates are based on US EPA exhaust emission certification data obtained by Yamaha. Your actual mileage will vary depending on road conditions, how you ride and maintain your vehicle, accessories, cargo and operator/passenger weight.
Wet weight includes the vehicle with all standard equipment and all fluids, including oil, coolant (as applicable) and a full tank of fuel. It does not include the weight of options or accessories. Wet weight is useful in making real-world comparisons with other models.
