However, it is not possible for Yamaha to test all nonYamaha accessories, nor control over their quality or suitability. Choose a genuine Yamaha accessory, or one that is equivalent in design and quality. Accessories should be rigidly and securely mounted.
● ● ● The more weight you carry, the slower you should go. Although conditions vary, it is good practice not to exceed 2nd gear whenever you are carrying heavier loads or when towing a trailer. Allow more braking distance. A heavier ATV takes longer to stop. Avoid making sharp turns unless at very slow speeds. Avoid hills and rough terrain. Choose terrain carefully. Added weight affects the stability and handling of the ATV.
