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. The riders depicted on this website are professionals, and all of the action was shot on a closed course. Side-by-Side (SxS) models are recommended for use only by operators 16 years with a valid driver's license. At Yamaha, we want every ride to be safe and enjoyable. There are few joys in life equal to the free-spirited thrill and experience of SxS riding. And that's why it's important for all of us to do our part as responsible riders. By following logical, common-sense rules, we can maintain season after season of unparalleled enjoyment of our sport. For your safety: Always wear your seat belt, helmet, eye protection and protective clothing. Avoid excessive speeds and never engage in stunt riding. Always avoid paved surfaces and never ride on public roads. And be particularly careful on difficult terrain. Never ride under the influence of alcohol or other drugs; it is illegal and dangerous. Always inspect your Yamaha before riding. Read the Owner's Manual and the product warning labels before operation. Yamaha recommends that all SxS riders take an approved training course. For SxS safety and training information, see your dealer or call the ROHVA at 866.267.2751
