The Rhino side-by-side ATV quickly became well-accepted by the outdoors community, for hunting, fishing, trail riding and working in the outdoors. New for 2006 Yamaha introduces the Rhino 450. This unit uses the same chassis, frame and body. The only features that have changed are the engine size and a reduction in gearing within the automatic transmission. Mated to the 450 engine is Yamaha’s tried and true Ultramatic automatic transmission with high, low, neutral and reverse. One of the only changes made to the basic components of the new Rhino is here. Yamaha changed and lowered the high and low gear ratio in the original Kodiak Ultramatic to increase the power level needed in a side by side application. A few other features that have trickled down from the Grizzly into both the Kodiak and Rhino are the On-Command Four-Wheel drive and the fully independent suspension., Let’s start with the On-Command four-wheel drive. First we have a dash mounted switch that enables the driver to in-gauge the machines four-wheel drive. If that’s not enough traction, Yamaha has another option. True locking four wheel drive. This locks all four wheels into a direct drive and produces power to each wheel. The system may sound complicated but its simple - just push the first four wheel drive button for four wheel drive. If that’s not enough, slide the locking lever over and push the locking differential button. This will engage the fully locked traction and supply power to each wheel. ,
