The Yamaha Grizzly 450->ke301 is the middle-tier member of Yamaha's Grizzly family. While it doesn't come with the simplicity of the entry models or the high-end specs of the top-of-the-line versions, it does offer a variety of features that has made a proven commodity.

The Grizzly 700-inspired front-end styling boasts plenty of unique details, including a convenient water-resistant storage compartment on the front fender. There are also steel cargo racks with a special paint finish that features a combined cargo capacity of 264 pounds; a large-capacity, 4-gallon fuel tank with a built-in gauge and easy-to-reach petcock valve; wide, fully integrated floorboards to keep riders' feet dry and feature serrated footpegs for extra grip in wet conditions; large front and rear fenders with inner guards that offer excellent mud/splash protection; and, dual, bright multireflector 30-watt Krypton bulb headlights with high and low beams.

The engine is a 421cc, 4-stroke, liquid-cooled single engine that comes with a semi-oval slide 33mm BSR Mikuni carburetor and a high-output DC-CDI ignition system that delivers tremendous throttle response and engine performance across the board. The whole technical set-up also includes a large-capacity aluminum radiator that provides maximum cooling

efficiency, a stainless steel muffler and header design that has superior

power characteristics, exhaust sound and durability, and a specially-designed drive system air intake vent that helps prevent overheating and keeps water and mud from entering drive case.

As far as handling is concerned, the Grizzly 450 has a lightweight chassis that has outstanding durability with superior rigidity for class-leading agility and handling. This is complimented by a fully independent four-wheel double-wishbone suspension that features a suspension on the front and rear, delivering 6.3" and 7.1" of travel, respectively. Large-diameter ventilated hydraulic front disc brakes deliver tremendous stopping power to round out the set-up of the sturdy Yamaha ATV.
