The Yamaha Rhino 700 Continues on the Popular Rhino SeriesThe Yamaha Rhino is one of the most popular recreational utility vehicles around. Back in 2003 (2004 model year), Yamaha introduced the Rhino 660. Later, in 2006, a lower cost 450 entry level model came along which offered a great value for the utility vehicle buyer. Unfortunately, the Rhino 450 was discontinued and now Yamaha only offers the Yamaha Rhino 700. The Yamaha Rhino 700 brings newer technology into the Rhino line up. The carbureted Rhino 660 has been replaced by the fuel injected Rhino 700. A larger 686 cc engine based on the Raptor design offers increased power output over earlier Rhino models. Also starting in 2008, all Rhino utility vehicles now come equipped with doors and additional passenger handholds for increased safety.
Mikuni fuel injection helps to ensure more precise air/fuel ratios throughout changes in temperature, altitude, and atmospheric conditions. The Yamaha Rhino 700 fuel injection system incorporates a Throttle Position Sensor (TPS) which feeds information to the ECU to be used in determining the right amount of fuel to be injected. Fuel injection helps improve overall drivability. If you've ever tried to start a Yamaha Rhino 450 or 660 (or any other carbureted vehicle) in very cold weather, then you probably know that it can sometimes be hard to get the engine running smoothly right away. The choke helps to get the engine running, but if you try to begin driving immediately after you start up, then you might experience some bucking and sputtering and even stalling. Once the engine warms up a little, then it will run just fine, but carbureted engines can be cold blooded. Thankfully, fuel injection eliminates these cold start problems as the injector is able to finely atomize the additional fuel needed under cold conditions.
Mikuni Fuel Injection Besides the addition of fuel injection, a new airbox design puts the air filter under the hood and reduces intake noise in the cab area. The new location of the air filter will also hopefully draw in cleaner air and reduce the amount of cleaning required of the oil soaked foam air filter element. Other improvements on the Rhino 700 include: 4 wheel disc brakes, new parking brake design, sport style steering wheel, cup holders, and new CV joint protectors. Another key improvement over the 660 model is that reverse is now geared lower to help ensure that the 700 has plenty of torque for backing out of difficult situations. It was hoped that the 2008 Yamaha Rhino 700 would be offered with Yamaha's innovative new Electric Power Steering (EPS), but for now this is not being included on the Rhino 700. This system incorporates an electric motor assist system that reduces steering effort by as much as 50% under certain conditions. Multiple sensors are used as input for the EPS control system, resulting in a variable assist that boosts steering assist at lower speeds, and reduces assist when it's less necessary at higher speeds. This variable, on demand power steering system greatly improves the driving experience, especially during low speed maneuvers in 4WD or full differential lock modes. It is currently offered on the Grizzly ATV and hopefully will be incorporated into future models of the Rhino. Under normal driving conditions, the steering effort on the Yamaha Rhino is very reasonable even without the power steering. Where power steering would be most beneficial would be in situations where the front differential is locked. With a long track record behind the Rhino and with the ongoing improvements, the Yamaha Rhino 700 continues to be the standard by which most other utility vehicles are measured.
